About the Team: Northeastern Electric Racing is a student-run organization from Northeastern University in Boston, Massachusetts. Our team of over 250 students builds all-electric formula-style race cars from the ground up. Each year, we compete against other universities in the Formula-Hybrid+Electric (FHE) competition at the New Hampshire Motor Speedway. In 2021, our first completed car won 2nd place in the Electric category, along with the Scrutineer’s Award for our excellent documentation and preparedness. Our Car: We began designing our first car, NER17D, in 2017. We spent the next 4 years developing our car to comply with the FHE competition rules. FHE is an engineering competition; much of our score is not on the performance of our vehicle, but on our engineering processes and documentation. At the competition, we are judged in two static events (design and project management) and compete in three dynamic events (acceleration, autocross, and endurance). Given that NER17D was our very first car, we were largely focused on getting it out the door. Over the four years it took to design and manufacture it, our team members learned as much as we could about the ins and outs of building a car for student formula competitions. By the time our car was running, we already had plenty of ideas for improving it. After our first competition in 2021, our engineering team began upgrading several systems on the car including its driver IO, suspension, motor cooling and with the help of PCBWay, our accumulator.Our PCBs: Upgrades for NER17D focus on reducing weight and volume, without significant redesigns to our fundamental electronics approach. Our biggest board is the HV PCB, which is located within our monolithic accumulator container. This board will reduce our occupied area by over 50% and potentially enable a significant weight reduction in the accumulator container.The HV PCB is responsible for regulating the primary current path and providing features such as precharge and discharge to enable safe high voltage and high current operation. Our vehicle requires currents over 200 amps, so the board has been designed as a 6 layer board with 3oz copper on all layers. Additionally, there are a number of large components that require a thicker than typical board to securely support. PCBWay is one of the few companies that provides numerous options for thicker final stackups, and heavy copper weights for all outer and inner layers, making PCBWay an ideal choice for this design. This board is our first attempt at moving critical power components to a PCB and our experience with this first board will be an excellent preparation for our next scratch vehicle, NER22. We do however plan for further PCB work in NER17D, such as the new wheel interface. This PCB has been specially designed for our new custom steering wheel and will enable flexible user IO via a selection of buttons and knobs that will be translated to signals and communicated via CAN. To optimize assembly, the board has been designed to only utilize a single side of the board and even keeps signals to a single layer. This board marks one of our first projects that is entirely dedicated to user experience enhancement, as opposed to pure vehicle performance.

Dear Sir/Madam,my name is Antonios Ntonas and I am reaching out to you on behalf of the Democritus University of Thrace and Democritus Racing Team (DRT) Formula Student Team. We are a university team that participates in international racing competitions with our own racecars. We are based in Xanthi, Greece and we have raced in Italy (2019), the Netherlands (2021) and Croatia (2022).So far we have been racing in the Combustion Vehicle category, but last year, taking into account the global industries' and the competitions' developments, and due to our passion for constant evolvement, we decided to develop an electric racecar to compete in 2022.Our first electric racecar competed in Formula Student Alpe Adria 2022 Competition, which took place in Croatia in August. This season we will take part in the Formula Student competitions which will take place in the summer of 2023, for example, Formula Student Netherlands, Formula Student East and many other competitions.We are determined to improve and set higher goals for our team, and we want to achieve this by building our second-generation electric race car, the DRT E-XR Evo! Your contribution would be crucial to our project. We would love to add PCBWay to our sponsor's list, were you interested in providing us, as a sponsor, with free printing of our PCBs. This sponsorship could help us greatly because PCBs are necessary for our project.Our team needs a total of 8 different PCB designs, which are necessary for our Tractive System, Safety Shutdown System and Vehicle Control Unit (VCU). These are:The Charger PCB is used in the charger for our High Voltage Batteries.The TSAL-Discharge and TSAL-Hoop LED PCBs. The TSAL-Discharge checks if high voltage is present in the car, if yes, it sends a signal to the TSAL-Hoop LED to light up some RED LEDs to warn people nearby to keep a safe distance, if not, it lights up some green LEDs in the TSAL-Hoop LED to let people nearby know that the car is safe.The DC/DC converter is a converter which drops down 560V from the accumulator to 60V so that it can be used in our low-voltage systems.The BSPD (Brake System Pausibility device) is a part of the shutdown system of the car, and it consists of a non-programmable circuit that prevents the driver from braking and accelerating at the same time, in order to prevent failures with stuck throttle pedals. The VCU, Vehicle Control Unit PCB is a PCB for the microcontroller ATMega 320P which controls the whole car.The Dashboard PCB receives necessary information like speed and state of charge and displays them to the driver through a small display.The Racecar Master does safety checks in the system and if it finds an error shuts the car down. It is also necessary for controlling the tractive system.Our designs will be ready in approximately early December, more specifically around December 7. We only want 3 copies of each PCB (one to use, one as a spare, and one to present to the competition judges), which we will assemble with our own components, on our own. Our team relies on sponsorships to achieve its goals. Therefore your contribution would be very important in our continuous and hard efforts to fulfil our goals.You can check out our site and social media at https://lob.ee/drt.Thank you for your time PCBWay!

We are the Carnegie Mellon University Formula SAE Team. We bring together the brightest engineers at Carnegie Mellon University to design and build a fully electric Formula style race car to compete with other university FSAE teams across North America.This summer, we first competed at the Formula Hybrid + Electric competition. At this competition, we won every static and dynamic event in the electric category and were awarded 1st Place Electric Vehicle Overall. Following that, we competed at FSAE Michigan where we came 2nd in Engineering Design, 2nd in Business Presentation, 2nd in Efficiency, and 5th Overall in the EV Class.We are currently designing and constructing our new 2023 car. We’re looking to make some key technical improvements such as a redesign for simplicity and reliability of our low-voltage control and battery management systems that include over 20 custom PCBs.Our GLV system is modeled off an automotive ECU distributed embedded system. What this means is that we have 8 custom boards that handle various functions on the car. For example, one of the boards is responsible for the driver interface and pedal sensors, another board handles the vehicle’s dynamics, another board handles the cooling of the powertrain, and another board handles the safety circuitry. An image of our controls and telemetry board is below. Our high voltage systems consist of a custom built 600V cylindrical cell battery pack with a custom battery management system. Our battery management consists of 8 boards each of which manages the voltage, temperature, and state of cell balancing of 90 cells for a total of 720 cells. One of the boards is shown below. We also have a custom high voltage backplane which provides mounting for various electro-mechanical devices and provides connections between some of our high voltage PCBs.In the future, for our 2023-2024 car, we hope to switch our battery pack architecture away from cylindrical cell towards pouch cells.

We are a university research project about robotics. This project specifically if focused on participating on the Small Size League (SSL) competition in the RoboCup. The SSL is a robot soccer league which aims to improve multi robot coordination through a soccer match. During a match, teams of 6, up to 11, robots compete using mostly standard soccer rules. During the game, the robots must act completely autonomous, there can be no human interference, except, only in a few cases, for the referee.In order to play a match the robot must be able to control five brushless DC motors (BLDC) and a high voltage board that is responsible forkicking the ball. All the needed electronics are built by the students that participate in the team.Each year, every team that wants to participate in the RoboCup must submit a video demonstrating the capabilities of their robot's and strategy software. The 2022 video can be seen below. More content can be seen in our youtube channel.In our electronic design we basically have two boards: main and kick. The main board is responsible for controlling the BLDC motors, processing the radio commands that come trough a nRF24L01 transceiver, activating the kick board, reading the ball sensor and regulatingthe voltages needed by the board components. The kick board is responsible for charging a high voltage capacitor up to 160V, and activating a solenoid coil, which is how the robots kick the ball.The new main board design is mostly focused on modularity and ease of development, therefore, the BLDC control is handled by a comercial electronic speed controller (ESC - https://www.st.com/en/evaluation-tools/b-g431b-esc1.html) and the main processing unit is a STM32 Discovery board (https://www.st.com/en/evaluation-tools/32f411ediscovery.html)

Campus Tirol Motorsport Formula Student Team from InnsbruckCampus Tirol Motorsport is a Formula Student Team made up of students from different Universities of Tyrol. Each year, we build an electric race car to compete in Events against teams from other Universities.Our team is relatively small and young, compared to many other Formula Student Teams. Nevertheless, in the last two years, we have managed to build cars that passed all technical inspections at the Formula Student competitions. At the Formula Student Netherlands Event we finished 12th, and at the Formula Student Austria Event we finished 14th in the electric vehicles class.Despite the small size of our Electronics team, we develop many systems ourselves from the ground up. We need to make sure they are rule compliant, fit our performance requirements and the mechanical size and weight constraints of a race car, which induces many self developed PCBs.A good example of this are the PCBs of our high voltage accumulator, which include the accumulator management system master PCB based on an STM32, which communicates over isoSPI with ASIC cell monitoring chips in each segment of the accumulator. The main accumulator management system is part of a PCB stack that includes our precharge board and the IMD. This stack reduces the mechanical footprint. The PCBs with the LTC6811 ASICs to monitor cell voltage and temperatures as well as to balance the cells are designed to directly fit on to the busbars that connect the series’ groups of cells to minimize the number of wires and connectors. With that, we increased reliability and minimized the packing space required.Our other self developed PCBs include our vehicle control unit, various PCBs to send sensor measurements over the car's CAN bus, the brake system plausibility device and tractive system active light which are required by the rules.This year we are switching from cylindrical to pouch cells in the high voltage accumulator, so our cell monitoring boards need an entire redesign to fit the new mechanical requirements. This is where we would like to use Flexible PCBs to completely eliminate single wires and have a solution that is robust against mechanical vibrations.Additionally, we are also starting to develop our own 600V 40kW motor driver based on Silicon Carbide MOSFET to have a more compact and efficient solution than the inverter we currently use from AMK.

University of Michigan SuperMileage is a student-run project team that is currently working to create two hyper-efficient vehicles to compete in Shell's Eco-Marathon competition. Our organization was founded in 2011 and currently has around 35 active members.This year, we are continuing development on our prototype-electric vehicle. We plan to add several electrical systems such as a speedometer, power sensing, current feedback sensing, adaptive PCB cooling, and wireless communication systems. We will also pursue another iteration of our driver board with a new microcontroller and industry standard motor control software.Our team is also developing a new urban concept internal combustion engine vehicle. We will utilize an adapted engine from a Honda Ruckus for our ICE. Our team is working very hard developing the mechanical systems, electrical systems, and body from scratch as we hope to compete this car spring 2023 at the Shell Eco-Marathon.

ABOUT OUR TEAMUNIUD E-Racing Team is a student group born at the University of Udine with the objective of designing and building an electric race car that will allow us to participate in the Formula SAE and Formula Student competitions.Website: https://formulasae.uniud.it/Linkedin: https://www.linkedin.com/company/uniud-e-racing-team/mycompany/Instagram: https://www.instagram.com/uniuderacing/THE PROJECTThe electronics department is tasked with designing all the control boards in the vehicle.Albeit it being a student project, our PCBs will still be part of an automotive environment, so they must:⦁ fit in tight spaces;⦁ be somewhat shielded from electrical noise;⦁ be resistant to vibrations and light mechanical shock.To achieve all these goals we decided to design multilayer_ed PCBs.OUR GOALS WITH PCBWAYWe would benefit greatly from a PCBWay sponsorship as it would allow us to get the professional-grade multilayer_ed PCBs we need to build prototypes and eventually compete as a team.At the moment we are looking for 4 layer PCBs with blind and buried vias, but moving forward we are planning to experiment with more exotic techniques such as flexible PCBs.As we progress into this journey we realize we will have to build many prototypes, and PCBWay fast production and shipping times would prove to be of great help to us.OUR CURRENT DESIGNS1. Telemetry boardThe telemetry board has to establish and maintain communication with the off-vehicle server, so it is supplied with a radio module and mounting holes for a custom antenna stand.A microcontroller module captures data flowing in through the CAN interface to elaborate it and send it to the radio chip.CAN communications are made possible by a CAN transceiver chip and the peripheral circuit surrounding it, provided with additional safety features such as ESD protection and EMI filtering.Two power rails (5V and 3.3V) are provided through cascaded buck DC/DC power converters.Since it is still in the prototyping phase, this board has been covered in test points so that it can be easily programmed and tested.2. Radio PC adapterThis device acts as an adapter that allows a server to communicate with the on-board car systems through radio. To execute this function the board is fitted with a radio module and all the peripheral circuits that allow it to communicate through USB.3. BSPD boardThe Brake System Plausibility Device is a non-programmable circuit required by the competitions we are going to attend. Its main purpose is to prohibit throttle and brake engagement at the same time, as to avoid mechanical failure.As of this moment, this board is still in development.

I have spent the last month in Fusion 360 designing my own combat robot. I have wanted to compete in various events and comps throughout Australia (Robowars Australia, Adelaide Robot Combat, Melbourne Combat Robotics) and have finally decided to build my own. So far, I have purchased the various drive components (motors esc's axels bearings wheels belts pulleys, ect) and similar for the weapon's drive. This in itself was quite expensive and cost around $300-$400. I Then realized that getting parts cnced was really expensive and there was no way my team could afford this. I then did some looking around and heard about PCBway from YouTube and that they do cncing and laser cutting.I have been watching Battle bots on TV for years now and I believe I have what it takes to design a very competitive bot.This is what the cad model looks like.Here are the components for the drive system on one side of the bot.This is an expanded view of all the components.Here is an expanded top view.Here is a side view.Here are some parts that will be cnced, these are the bearing holders.Some of the aluminium frame parts, they will be welded together.

About the TeamSociety of Robotics and Automation (better known as SRA) is a well-established, non-profit, student-driven organization in VJTI, Mumbai. It started in September 2008, and deals with Robotics, Embedded Systems, CAD Design, Kinematics, Mechatronics, Automation, Machine Vision, and other allied fields.We are trying to develop our first Half-size Micromouse and compete in robotic competitions conducted all over the world.About The ProjectMushak is a micromouse maze solving bot. The aim of this project is to make India's first and smallest half-size micromouse bot. "Mushak" in hindi means "Mouse".This micromouse consist of a very small coreless motors (6 mm width and 10 mm length) and PCB as it's base . Since coreless motors doesn't provide enough torque for the movements of bot we used gear box to increase the torque.Mushak is of size 45.7mm x 40.0 mm, which is smaller than similar micromouse using STM32F405RG. We boast of least area consuming micromouse made using STM32 LQFP64 package chips.The Mushak PCB design is made on the latest version of KiCAD 6.Mushak is designed over STM32F405RG microcontroller accomodated with various sensors and drivers for the micromouse.We designed the smallest micromouse that is based on STM32F405RG microcontroller.Major components used in the PCB include -STM32F405RG MicrocontrollerVL6180x ToF sensorDRV8833 Motor DriverMPU6500 IMUSFH-4045N Infrared EmitterSFH-3015-FA Phototransistor (Reciever)IR sensorsThe IR sensors include majorly two components, IR emitter which emits the Infrared light of a particular wavelength which is not visible with the human eye.This light gets reflected back from the obstacle present in form of the robot to the photo transistor, when the Infrared light of this perticular wavelength enters the phototransistor device it allows the current to flow from the collector to the emmiter of device. This current flow creates a voltage drop across the resistor connected with the photo transistor and this voltage drop is read by th ADC of the microcontroller which varies as the intensity of light reflected changes. By this way we can determine how far is the obstacle from the robot.For controlling the intensity of the transmitted light we used N-Channel Mosfet whose gate is controlled by PWM signal given by the microcontroller. By varying the PWM duty cycle we can control the intensity of the transmitted light from IR emmiter by which we can control the distance sensitivity.Four Sensor pairs are being used in Mushak (Micromouse)Placement of IR SensorsPlacing IR sensors pose a challenge, and required rigorous testing and brain storming.As can be seen in the image above we have visualised 2 cell based maze and bot is placed in first cell.IR1 (blue rays) is pointing to the left mid point of next cell.IR2 (orange rays) is pointing to the left end of current cell.IR3 (pink rays) is pointing to the right end of current cell.IR4 (green rays) is pointing to the right end of current cell.To move the bot in straight line along the diagonal maze pattern , we have considered point 1 and point 2. These two points are the edges of diagonal ends of above pattern . So if bot had to move diagonally we can check for readings at these two points and control the bot accordingly.Power DistributionPower to the control circuits is provided by 3V linear Regulator(LDO) which can provide upto 1A current. Power to the motor is directly given to the motor driver through battery.Additional capacitors are added across outputs for filtering out the voltage. Voltage divider resistors are being used to monitor the battery voltage. Power indication LED has been provided in the PCB. The input voltage for the PCB is 3.7 voltage through a general LiPo battery.STM32F405RG (Microcontroller)The below image shows the pinout of STM32F405RG that we will be using for this project :Decoupling capacitors of 0.1uF are connected near the vdd pins of STM32. Additional external low and high frequency oscillators are added for precise timing.HSE(High Speed External) clock - 25 MhzLSE(Low Speed External) clock - 32.769 KhzFilter circuit is being used for filtering out the analog reference voltage. Additional Debug switches are being added for debugging purposes.DRV8833 (Motor Driver)We have used H-bridge motor driver which can control two motors at the same time via PWM (pulse width modulation) from the STM32F405RG (microcontroller).The motor driver can supply 1.5 Amps of current per motor which is enough to power up the coreless motors.This motor driver keeps the controls terminals from the microcontrolller isolated from noise and high volatages of the motor power supply.VL6180X (ToF Sensor)We added a Time of Flight sensor in front of the robot to measure the distance of the obstacle in front from the robot.This sensor measures the time taken by the light signal to get reflected from the obstacle and then measures the distace of the obstacle from the robot.The sensor uses I2C protocol for communication with the microcontroller and send the distance values. It also has an additional feature of sensing the ambeint light which we can use to avoid the problems faced with IR sensors due to varing ambient light conditions.Due to cost issues it is not feasible to replace IR sensors with VL6180x, else it could have been a replacement.HC-08(Bluetooth Module)We used a BLE(Bluetooth Low Energy) module to communicate to the robot. It is one of the most important modules that is being used in mushak, this bluetooth module will enable us to communicate with the robot and precisely tune it to solve the mazes, additionally it makes debugging easier for us making Mushak user friendly.The module consumes very less power(since it works on BLE) and works on UART communication to talk with the microcontroller.For attaching this module we have provided the JST connectors to connect this module externally when required.AS5600 (Magnetic Encoder)To measure the RPM and the distance that the robot has covered we needed a type of encoder feedback. For this we used AS5600 magnetic encoders to measure the amount of rotation of the robot wheel.The magnetic encoders are mounted in an innovative way due to which no external mounts were required for their placement. Since magnets need to be right infront of the IC of AS5600 to get proper reading, we have taken extra care with mount size and shaft placement.The sensor works on I2C communication protocol to provide the reading to the microcontroller.MPU6500 (IMU)This sensor gives the feedback of orientaion of the robot. This MEMS based chip has in-built Acclereometer and Gyroscope by which it can determine its orietation with respect to space.This sensor works on SPI as well as I2C communication protocol but in our case to get the fastest data transfer, we used use SPI communcation.RoutingFront Copper Layer:Back Copper Layer:Final Routing:For routing of the control circuitry we used traces of 0.2mm width and for power connections we used 0.4mm width tracks to ensure fairly high current flow.Solutions to some of the major problems faced while designing PCBMinimalising passive components is a really hard task. So to solve this I properly reffered the application notes and datasheet of stm32f405RG. Moreover the design is well tested on simulation platform.Efficient placement of components to reduce the size of the PCB. Innovative design to fix sensors and encoders in such a small space.Since IRs are sensitive to ambient light we required a mechanism to adjust the brighness of IR Emitter. So to do that we used a mosfet based circuit, so brightness can be controlled using PWM.It was a big challenge to place 90+ SMD and THT components on a small size PCB of just 45.7x40mm size.Issues Faced in Mechanical DesigningDesigning MountIssue : The main issues faced in designing the Mount were As the Gears acquired were of a smaller diameter, there was an issue of interference between the bearing and the motor. As they were too close, it was impossible to 3D print a mount with the thickness less than 1mm.Solution : The solution opted for this was to actually disalign the motor and the shaft to give room the bearing housing to be 3D printed. This enabled us to print a more stable base due to the stronger Shaft housing. Below images demonstrate how it was done.Finalising and Meshing the gearsIssue : As there are a varieties of gears available. It was hard for us to choose the right combination and Built the Model and mounts around it.Solution : We started with finalising the sizes and the gear ratios needed according to the available spaces. We then did the market research to find the gears closest to our needs and incorporated those models into the Design.

BME Formula Racing Team is a team of university students who design and build single seater, formula style race cars and participate in Formula Student, an international constructor competition series for students. This complex project, which includes designing, manufacturing, testing and racing a race car, as well as the management of a team, helps students put theory into practice in a competitive environment and develop a wide range of technical and problem-solving skills through direct experience.We would like to achieve better results year by year competing in the high-level international field of Formula Student. OUR STORY The team was founded in 2007 at TU Budapest with the purpose of participating in the international Formula Student series. We are proud to be the pioneers of Hungary’s FS teams. We do our activities within the legal frames of the Formula University Public Benefit Organization (since 2008).The work of the team involves the design, procurement, manufacturing and building of the race car, as well as solving logistical, economical, and managerial issues. At the beginning, BME FRT made cars powered by gasoline, but since 2011 we have been the first and only team in Hungary to race in the more environmentally friendly electric category. In 2018 we constructed the first self- driving race car in Hungary as well. OUR RECENT ACHIEVEMENTSIn 2022, we take part in 3 Formula Student races, and had a successful season, finishing third on the podium in the electric category at Formula Student Germany. We also competed in the driverless category in 2 of our races, showing a high level of improvement compared to last year.OUR GOALS WITH PCBWAYWith PCBWay we are looking for professional high quality multilayer_ PCB manufacturing. We are hoping to manufacture our first 6 Layer PCB and also we would like to add flexible PCBs to our projects, so we can integrate our electronics even better into our race car.OUR PCB DESIGNSMain ECUCAN NodeOUR SOCIALSWebsite: https://frtbme.hu/Facebook: https://www.facebook.com/FormulaRacingTeamInstagram: https://www.instagram.com/bme_formularacingteam/LinkedIn: https://www.linkedin.com/company/bmefrt/mycompany/

Who we areGator Motorsports is the University of Florida's Formula SAE team. Every year we design, build, test, and compete with an advanced racecar against 100 other universities. In May of 2022 we competed with our 31st and last internal combustion car and placed 3rd overall. For 2023, the team is working on developing our first electric vehicle.The Power Distribution ModuleThe car has many low-voltage components that need to be supplied from the low-voltage battery. Usually, this is done through a fuse box but that doesn't provide any control or monitoring of the component's power usage.This 16-channel power distribution module was made to replace a fuse box in a race car. It consists of 16 individual channels and can carry a continuous current of 90A, with expected transients totaling over 130A. Each channel's voltage and current are monitored at over a thousand times per second, and the energy use is calculated by a microcontroller. This data is sent over SPI directly to the data logger, as CAN would be too slow. This module also generates various voltage rails through two 2-channel buck converts, which are used by the vehicle controller.Each channel consists of a power monitoring IC, a shunt resistor, and an eFuse IC, which limits the current in hardware. The current limit can also be lowered in software because of the fast current monitoring. Each channel has features such as dv/dt control, PWM, and temperature monitoring.

Who we are, and what we're doingWe are team of lectuers at freetime electronic club for kids in Lužánky Brno.Every school year multiple times a week we have freetime club meetings with kids interested in electronics and programming from 10 to 18 years old. The electronics club usually have about 20-25 kids .We as a tem have to make sure that these kids will have best experience possible, which is in our experiences come from making some sort of long-time project requiring lots of soldering and patience to get it to work. Last year we prepared fully programmable LED matrix display whose construction took large portion of school year.Club meeting usually consists of theoretical part and constuction part. In theoretical part we try to explain function portion of circuit they are about to solder etc. After they solder their circuit we usually test the circuit via osclilloscope and multimeter so kids get confortable using these instruments.Project Descript__ionThis year we watned something big and interesting, as mentioned above our best bet for last year was big matrix LED display, but beacuse many kids in our club remain for many years we cannot make same project every year. so we decided to design this analog synth.The synthetizer itself consists of many separate modules connected only by supply traces on one PCB, and by connecting signals from and to those modules with external wires via inserting them to sockets we can make almost any combination of different modules to make unique sounds and beats. The synth consists of:Differential power supply delivering 12v and -12vRaspberry pico with MIDI in and out extension, 4x PWM to analog converters and 3x ADC inputs2x stylophone-like resistor divider rails2x exponential VCO (voltage controlled oscillator)2x LFO (low frequency osclillator)2x envelope generator3x VCA (voltage controlled amplifier)2x drum-like oscillator2x signal mixersoft signal clipperwavefolderresonant diode bridge low pass filterresonant diode bridge high pass filterI2C OLED display6x cherry MX mechanical keyboard switches with LED3.5mm jack output or automatically selected class AB speaker output amplifierlots of LEDsGPIO pin header for extensions (9 free GPIOs)It is quite easy to 3d print extension like keyboard instead of stylus, which would make this synth more piano-like.Its 12V input and quite low power consumption (<100mA) makes it possible to be powered by batteries.If you have any quescions or advices feel free to contact us.Words to PCBWayWe are hoping PCBWay will be able to help us by sponsoring our analog synthetizer board. We have put countless hours in the careful design, and re-design of this board to make full use of PCBWay's manufacturing capabilities. We hope that this is enough to convince PCBWay to manufacture us these boards which woud othervise cost us about 190$ for 25 boards, which would otherwise upset our yearly budget for our electronic kids/students.Render in Fusion 360Board in Eage

About us:PARS Rocket Team is a student team operating within Istanbul Technical University. Our team consists of students who are willing to work in the field of space. Founded in 2012, the purpose of our team is to design and build rockets powered by hybrid propellant engines. We are preparing the test stand we have developed for this purpose for the tests of our new hybrid propellant rocket engine that we are developing.About the project:The measurement and control unit of our test system is the PARS Data Acquisition System(DAQ). PARS DAQ is a data acquisition unit designed to measure and store pressure and temperature data from engine in the test process and open and close the valve in the system.The system powered by two 3S Li-Po(24V) connected in series, so it doesn't need an outlet to work! STM32F407VG was chosen as a microcontroller in our project because it has enough GPIO outputs, high FLASH Memory and Ram capacity. However, the loadcell reading of our system is carried out with a secondary microcontroller (STM32F030F4P6) for load sharing and provide better timing.The sampling rate of 4 loadcells on PARS DAQ is 100kbps and the ADC resolution is 12 bits. 15 bit ADC resolution data can be obtained from 4 thermocouples. At the same time, 3 encoder readings can be made and the position information of 3 DC motors can be obtained for valve control.PARS-DAQ is remotely controlled and customized to close the valve in the system in case of emergency. With the SD card on Pars DAQ, it can instantly write sensor data on an embedded SD card. In this way, even if a problem occurs in the system, data loss is prevented. Thanks to the Bluetooth module inside, it can send the recorded data to any Bluetooth receiver!Also, PARS-DAQ has a modular system and is always suitable for adding new modules!We need PCBWAY's support to manufacture these modular circuits. Thank you for helping hardworking students with big dreams in space by supporting us!
