Find your board. Understand every pin.

Discover. Identify. Build.

MCUID connects microcontrollers, modules, development boards, pinouts and hardware revisions. Every published field carries a fixed official source, so you can verify what a pin does — and when a board revision changes it — instead of trusting a copied pinout image.

Start with the first qualified board: the ESP32-S3-DevKitC-1, or read About MCUID.
