Start wiring

USB · 3.3 V

Confirm the data interface matches your host board.

Module pins: P0, P1, P2, P8, P12, P16, Motor1 +/- or DIR/PWM, Motor2 +/- or DIR/PWM. Schematik maps them to your board in the app.

Other MCUs

228 other options

Specialists: Teensy for high-clock audio and USB, Adafruit SAMD boards running CircuitPython or the Arduino IDE, proper STM32 eval kits, and the micro:bit classroom ecosystem. Schematik builds target ESP32, Arduino Uno, and Pico; come here when you have a specific reason to.
