Verify supply voltage and logic levels before powering up.
Module pins: 3V / 5V (from micro:bit), GND, Sensor / Line follower inputs, LED / Buzzer outputs. Schematik maps them to your board in the app.
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.
