FireBeetle 2 ESP32-C6 IoT Development Board

The FireBeetle 2 ESP32-C6 from DFRobot is a low-power IoT board with the RISC-V chip ESP32-C6 (160 MHz, 4 MB flash). It communicates via Wi-Fi 6 in the 2.4 GHz band, Bluetooth 5 (LE), Zigbee 3.0 and Thread 1.3, which makes it suitable for smart home devices, also to the Matter standard. It is powered via USB-C, with 5 V at the VIN pin or with a 5 V solar panel. A CN3165 charge controller charges a connected lithium battery, the battery voltage can be measured at pin IO0.
