XIAO ESP32C6 Pinout

The XIAO ESP32C6 is the wireless-mesh member of the Seeed Studio XIAO family. It keeps the thumb-sized 21 x 17.8 mm XIAO outline and the single-sided component layout, and is built on the Espressif ESP32-C6 SoC with 512 KB of SRAM and 4 MB of flash.

The ESP32-C6 combines two 32-bit RISC-V processors: a high-performance core running at up to 160 MHz and a low-power core clocked at up to 20 MHz. Its radio covers 2.4 GHz Wi-Fi 6 (802.11ax), Bluetooth LE 5.3 and IEEE 802.15.4, so the board speaks Zigbee and Thread as well as Wi-Fi, and is Matter native. According to Seeed, it is the first XIAO member compatible with Thread.
