FireBeetle 2 ESP32-C5 IoT Development Board

The DFRobot FireBeetle 2 with the ESP32-C5 uses dual-band Wi-Fi 6 on 2.4 and 5 GHz, according to DFRobot as the first Espressif chip, plus Bluetooth 5, Zigbee 3.0 and Thread 1.3. This makes it suitable for custom devices in Home Assistant via MQTT or Zigbee and for Matter over Wi-Fi or Thread. A charger with solar input for 4.5 to 6 V and a deep sleep current of 21 µA make it suitable for sensor nodes without mains power.
