Gotchas to know
- It ships with an external u.FL antenna that you must attach (and set the RF switch) for usable range.
- Only 11 castellated GPIO; you solder headers or use the XIAO expansion board.
- No PSRAM and 4MB flash: fine for sensors, tight for camera or AI work.
- Thread/Zigbee (802.15.4) needs the right stack and firmware; it is not plug-and-play with classic Wi-Fi sketches.
Variants
Same footprint as the XIAO ESP32-S3 and ESP32-C3, so it is pin-compatible with the wider XIAO accessory range.
The ESP32-C6 inside
This board is built on the ESP32-C6 . See the SoC page for the full peripheral, GPIO and security details.
