About this board

Seeed’s thumb-sized ESP32-S3: the same S3 silicon as the DevKit with only the pins that fit on a board the size of a thumbnail. Code is interchangeable — what changes is which GPIO numbers exist, so check the map below before moving a sketch across.

This is the plain XIAO S3. The camera-and-microphone variant is a separate board, XIAO ESP32S3 Sense.

No separate starter: open New ESP32-S3 project and swap the board, or place it from Add Component.
