DESCRIPTIONI am a member of the Swedish team Chalmers Formula Student. As you might know already, Formula Student is the largest engineering competition for students, challenging university teams from across the world. The product, a formula style race car, that must face rigorous dynamic events.Chalmers Formula Student has established itself as one of the top teams in the world, cinsistently receiving high scores due to our efficiency in working with limited resources and fewer engineers than other top teams. We are the most efficient team, and we are able to compete thanks to our valuable partners.TECHNICAL DETAILSWe designed several pcbs for our racecar:4 nodes which work as ECUs and analyse and log all the data. They are connected via can2 carrierboards connected to the battery cells to reduce wiresSlave for the battery management systemBSPD (brake system plausibility device) to check for brake system failures2 motherboards to reduce wiresTSAL (tractive system active light) to flush a light when high voltage is onSteering Wheel to get the data from the buttons on the steering wheelFuseBox to fuse all the low voltage power connectionsProcessor where the processors of the nodes are put on (we use the same processor for all nodes)LEDdriver to control the brake lightWords to PCBWayWe have ordered our pcb last year at PCBWay and were really happy with your service so we want to continue ordering our pcbs at PCBway. We would not be able to build a racecar without the support of our partners and would really appreciate if you could support us.

### DESCRIPTION ( Introduce yourserlf and your project)Hello!I am an FPGA enthusiastic and nowadays I am trying to make an transmitter which uses optical interface. I have an FPGA evaluation board, and I am trying to use it as a transmitter. The evaluation board has 1 SFP+ connector yet I need 8 in total. So I have designed a PCB which converts the MOLEX backplane connector to 7 different SFP+ connectors. The purpose is to be able to convert 8 electrical channels of the FPGA to optical channels. Evaluation board has 1 SFP+ connector as I mentioned before.### TECHNICAL DETAILS (With project photos)I am using SFP+ to convert electrical signal to optical signal then I transmit them via optical fiber.Picture of the Evaluation boardA picture of SFP+ module.Picture of the female Molex Connector at the FPGA evaluation board and the Picture of the male Molex Connector which will be mounted to the PCB I have designed.A picture of SFP+ cage which will be mounted to the PCB.### Words to PCBWayI have been looking for different PCB suppliers for a long time and I think finally i have found one I can trust. I have already suggested your company to many of my friends. Please let me have 8 Optical channels with your sponsorship PCBWAY =).Best RegardsIbrahim Sezgin

Project Introduction: We are two guys doing our degree project in industrial design. The project is about making and designing att new wireless speaker. We are also designing the electronics and need prototype for final presentation. Any sponsoring would be great and 30% on further prototypes would be highly appreciated! Project Details We are using a RN52 bluetooth module, ADAU1701 DSP and TPA3116 amplifier chips. The pcb needs to be 4layer and aprox 100x100mm, we need 5-10pcs for first prototype. Below is a schematic.
