This is my control board for automatic blinds. It is very easy controller which you can easy reprogram for yourself by UART. Only what you need is FTDI232 programer. I used DC-DC buck converter for set voltage on each motor. The heart of the controller is ATMEGA 8 but I recommend ATMEGA 328 because she has more memory. I had to remake IR library because this library take up all memory of microprocessor.Link for 3D print parts(my own project): https://www.thingiverse.com/thing:2861860Screw terminal block connector:X2: 1 - 12V DC 2 - GNDX3,X4,X6,X7 - End stopX5,X8 - Motors

Simple board for your stepper motor. If it does not have a connector but permanently attached cables, you can use it as an adapter.Holes for interweaving the cables to make them sit tight and a standard 2.5mm JST connector. You can use 4 or 5 pin if you have a shielded cable.

Hi, I AaquI am 20 years old, I am a hobbyist and I come from PolandWhen I surfed the internet, I found the OSTR(Open Source Turtle Robot) project. Decided to add buttons and a display for easy control. The project is designed to introduce to the secrets of programming.?Original projectOSTR - https://www.instructables.com/id/OSTR/, https://github.com/aspro648/OSTR?OTTO DIY - https://www.ottodiy.com/I record part of the process in the form of short vlogs.

### DESCRIPTIONPCB is a part of my robot which purpose is to solve SLAM algorithm problem. Hussar_redSLAM is a high performance mobile robot with a huge amount of sensors control by microcontroller STM32F103VCT6 on the pcb board. Mechanic parts were printed on the 3d print, painted by spray (red, black and invisible color) and assembled all together. Robot has got 2 wheels ( 2 class robot) with 2 ballcasters .Robot conntected to PC via Bluetooth connection and control by dedicated aplication write in C#.HUSSAR has got its own panel : LEDS, OLED display and 5way tact swich joystick.### TECHNICAL DETAILS / COMPONENTSUsed microcontroller : STM32F103VCT6Sensors modules : MPU6050, Pololu LSM303D + GY-271(HMC5883l), Pololu MinIMU9v5 (I2C)Distant sensors : 1x SHARP GP2Y0A21YK0F, 5x Sharp GP2Y0D810Z0F, 2x Sharp GP2Y0A51SK0F, 1x HC SR04Other modules : microSD module (SPI), RFM69HW (SPI), IR receiver, Bluetooth HC-05 (SLAVE).Battery : Lipol 2S and 2032 battery for RTCMotors : 150:1 HPCB micro pololu motors with dedicated magnetic encodersMotors controlers : 2x TB6612 modulePower : 5V and 3V3 voltage regulator LSM1117 + LittleFUSE 5AServo : microServo redox S90BuzzerJST ZH 1.50 mm connectors 2 - 8 pinsWeight : about 400 gramsSize : a regular geometry with a diameter 12 cm, height about 12 cmContruction : PLA, metal### COMPONENTSPart Value Package Library BOOT0 JP2 jumper BOOT1 JP2 jumper C1 100uF CT6032 rcl C2 22uF A/3216-18W rcl C3 100nF C0805 rcl C4 100nF C0805 rcl C5 100nF C0603 rcl C6 100uF CT6032 rcl C7 100nF C0805 rcl C8 100nF C0805 rcl C9 100nF C0805 rcl C10 22uF B/3528-21W resistor C12 22uF B/3528-21W rcl C13 100nF C0805 rcl C14 10uF C0805 rcl C15 100nF C0603 rcl C16 0.1uF C0805 rcl C17 4.7pF C0805 rcl C18 0.1uF C0805 rcl C19 22uF B/3528-21W resistor C20 4.7pF C0805 rcl C21 100nF C0603 rcl C22 100nF C0603 rcl C23 100nF C0603 rcl C24 100nF C0603 rcl C25 100nF C0603 rcl C26 10/47uF B/3528-21W resistor C27 10 /47uF B/3528-21W resistor C28 100nF C0603 rcl C29 100nF C0603 rcl C30 100nF C0603 rcl C31 100nF C0805 rcl C32 100nF C0805 rcl C33 100nF C0805 rcl C34 100nF C0805 rcl C35 47uF B/3528-21W rcl C36 47uF B/3528-21W rcl C37 10uF A/3216-18W rcl C38 10uF A/3216-18W rcl C39 22pF C0805 rcl C40 22pF C0805 rcl C41 22uF B/3528-21W rcl C42 10nF C0805 rcl C43 1uF C0805 rcl C44 1uF C0805 rcl C45 10nF C0805 rcl C46 100nF C0805 rcl C47 100nF C0805 rcl C48 100nF C0805 rcl C49 4.7uF A/3216-18W rcl C50 100nF C0805 rcl C51 100nF C0805 rcl C52 22uF B/3528-21W rcl C53 10uF B/3528-21W rcl C54 22uF B/3528-21W rcl C55 22uF B/3528-21W rcl D1 DO214AA diode D2 DO214AA diode DDD 8MHZ CRYSTAL_QSDG8M000_SJK crystal_QSDG8M000_SJK IC1 LM1117IMPX-5.0 SOT223 lm1117 IC4 LM1117IMPX-3.3 SOT223 lm1117 L5 10uH L0805 rcl_inductor LED1 CHIP-LED0805 led LED2 CHIP-LED0805 led LED3 CHIP-LED0805 led LED8 CHIP-LED0805 led R1 1K M0805 resistor R2 1K M0805 resistor R5 1.5K R0603 rcl R6 100K M0805 resistor R7 10K R0805 rcl R8 100K M0805 resistor R9 10K R0805 rcl R10 10K R0805 rcl R11 10K R0805 rcl R12 10K R0805 rcl R13 1K R0603 rcl R14 1K R0603 rcl R15 1K R0603 rcl R16 1K R0603 rcl R17 1K R0603 rcl R18 1K R0805 rcl R19 2K R0805 rcl R21 1M M0805 resistor R22 10K M0805 resistor R23 330 R0805 rcl R24 10K R0805 rcl R25 4K7 R0805 rcl R27 4K7 R0603 rcl R29 1K R0603 rcl R30 1K R0603 rcl R31 1K R0603 rcl R32 1K R0603 rcl R42 1K R0603 rcl R43 1K R0603 rcl R44 1K R0603 rcl R45 1K R0603 rcl RESET DTSM-3 DTSM-3 switch-tact
