A development board from DFRobot based on a ESP32 microcontroller by Espressif. Thanks to the built-in USB connector, it is easy to program. For extra connectivity, the board has multiple wireless communication interfaces (including Wi-Fi/Bluetooth). Finally, the board has a battery connector where a Li-Po/Li-ion battery (not included) can be connected, which can also be charged via the board.
