Start wiring

Shield

Verify supply voltage and logic levels before powering up.

Module pins: 5V, GND, TXD / GPIO14, RXD / GPIO15. Schematik maps them to your board in the app.

Add-ons

269 other options

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.
