Beetle ESP32-C6 Mini Development Board

The Beetle ESP32-C6 from DFRobot is a mini board measuring 25 × 20.5 mm with the RISC-V chip ESP32-C6. It communicates via Wi-Fi 6 in the 2.4 GHz band, Bluetooth 5 (LE), Zigbee 3.0 and Thread 1.3 and charges a connected lithium battery with up to 0.5 A. The battery voltage can be measured by the program. 13 digital I/O are enough for buttons, sensors, small displays and LEDs in wearable devices and small smart home projects.
