Verify supply voltage and logic levels before powering up.
Module pins: VIN, 5V, 3.3V, IOREF, GND, D0, D1, D2. Schematik maps them to your board in the app.
About 75 boards across every Arduino generation: 5V Uno/Mega/GIGA, 3.3V MKR and Portenta, plus DFRduino and Bluno compatibles. Confirm the voltage rail before stacking any shield.
