M5Stack NanoC6 (C125) – ESP32-C6 board (Wi-Fi 6, Zigbee, Thread, Matter)


 

 


The NanoC6 is M5Stack's smallest development board with the ESP32-C6, the chip behind much of what is new in smart homes. It supports Wi-Fi 6, Bluetooth 5, Zigbee and Thread, so the same board can work as a classic Wi-Fi sensor or as a Thread/Matter device.

The board is tiny, powered over USB-C, and has a built-in RGB LED, a button and a Grove port for connecting sensors without soldering.

Works with

  • ESPHome (esp32-c6 with the ESP-IDF framework)
  • Home Assistant via ESPHome or Matter
  • Arduino IDE and PlatformIO
  • UIFlow (M5Stack's block programming)

Good to know

The ESP32-C6 needs ESP-IDF in ESPHome, not the Arduino framework. Example configurations are in M5Stack's product documentation (link below).

You also need

A USB-C data cable (not charge-only) and, to connect a sensor, a Grove cable.
