About this board

The XIAO ESP32S3 with the Sense expansion: an S3 the size of a thumbnail that also carries a camera, a PDM microphone and a microSD slot. All three are emulated, so the sensor projects produce real data rather than placeholders.

If you want the plain S3 without the sensor board, that is XIAO ESP32-S3.

• Camera photos to microSD — the camera and the card together, which is what the Sense is for.
• PDM microphone level and on-board microSD take one peripheral at a time.
