Confirm the data interface matches your host board.
Module pins: External Power, Servo Power, VCC (5V/3.3V), GND, Serial, Analog Input Pins, I2C Port, SPI Port. Schematik maps them to your board in the app.
About 270 add-ons across Pi HATs, Arduino shields, and FeatherWings. The same function — motor control, PoE, display — usually ships once per host connector family. Get the host board right first.
