At just 21×17.8mm — smaller than a thumb — it integrates an ESP32-C6 SoC with dual RISC-V cores (160MHz high-performance + 20MHz low-power), WiFi 6, Bluetooth 5.3, Zigbee, Thread, and Matter connectivity. Security is built in at the hardware level: secure boot, flash encryption, identity protection, and a Trusted Execution Environment (TEE) are standard on the ESP32-C6. Combined with Matter's cryptographic commissioning model, this makes the XIAO ESP32C6 suitable for production-grade smart home products, not just prototypes. The onboard high-performance ceramic antenna provides up to 80m range for BLE and WiFi, while a U.FL connector allows connection to an external antenna for extended range. Deep sleep current of just 15µA enables long battery life in sensor applications. A battery JST connector is provided for portable applications. With 11 GPIO supporting PWM, I2C, SPI, UART, and 7-channel ADC, plus compatibility with the entire Seeed Grove sensor ecosystem, the XIAO ESP32C6 supports ESPHome, Arduino, MicroPython, CircuitPython, and ESP-IDF for maximum firmware flexibility. ## Where to Buy - [Seeed Studio](https://openhardware.directory/r?to=https%3A%2F%2Fwww.seeedstudio.com%2FSeeed-Studio-XIAO-ESP32C6-p-5884.html&ref=openhardware.directory&product=seeed-xiao-esp32c6&source=md-export) — 5.40 ## Resources - [product](https://openhardware.directory/r?to=https%3A%2F%2Fwww.seeedstudio.com%2FSeeed-Studio-XIAO-ESP32C6-p-5884.html&ref=openhardware.directory&product=seeed-xiao-esp32c6&source=md-export) - [wiki](https://openhardware.directory/r?to=https%3A%2F%2Fwiki.seeedstudio.com%2Fxiao_esp32c6_getting_started%2F&ref=openhardware.directory&product=seeed-xiao-esp32c6&source=md-export) - [datasheet](https://openhardware.directory/r?to=https%3A%2F%2Ffiles.seeedstudio.com%2Fwiki%2FSeeedStudio-XIAO-ESP32C6%2Fres%2Fesp32-c6_datasheet_en.pdf&ref=openhardware.directory&product=seeed-xiao-esp32c6&source=md-export) - [schematics](https://openhardware.directory/r?to=https%3A%2F%2Ffiles.seeedstudio.com%2Fwiki%2FSeeedStudio-XIAO-ESP32C6%2FXIAO_ESP32_C6_v1.0_SCH_260114.pdf&ref=openhardware.directory&product=seeed-xiao-esp32c6&source=md-export) ## Tags `esp32-c6`, `xiao`, `wifi6`, `thread`, `zigbee`, `matter`, `ble`, `tiny`, `seeed-studio`, `low-power`, `secure-boot` ## Images ![Seeed Studio XIAO ESP32C6](https://nbg1.your-objectstorage.com/openhardware-directory/entities/seeed-xiao-esp32c6/05b4494774f4.jpg) ![Seeed Studio XIAO ESP32C6](https://nbg1.your-objectstorage.com/openhardware-directory/entities/seeed-xiao-esp32c6/2928100961d9.jpg) ![Seeed Studio XIAO ESP32C6](https://nbg1.your-objectstorage.com/openhardware-directory/entities/seeed-xiao-esp32c6/e16690435601.jpg) > **Battery Powered:** Li-Po --- [View full device page](https://openhardware.directory/devices/seeed-xiao-esp32c6)
