This development board is an ESP32 based board with WiFi and Bluetooth. The board has a built-in 18650 battery holder and a Li-ion charge and discharge circuit with which you can power the microcontroller. The CP2102 USB to serial converter and USB connector makes it easy to program, even as an Arduino. Moreover, the board can be powered and the battery can be charged via the USB connector. The board comes with separate headers.


  • ESP32 chip with 512kB RAM (240Mhz dual core processor)
  • Flash memory: 4MB
  • Up to 26x digital pins (all with PWM capability)
  • Up to 16x analog (ADC) pins
  • Two analog (DAC) outputs (pin 25 DAC1 and pin 26 DAC2)
  • 1x SPI, 1x I2C, 1x UART (TX/RX)
  • Built-in 18650 battery holder (battery not is included)
  • Built-in Li-ion charge and discharge circuit
  • Micro USB connector
  • Power switch
  • Dimensions: 92 x 30 x 20 mm (without headers and battery), 92 x 30 x 25 mm (without headers, with battery)
  • The pinout is printed on the board and can be seen in the images (Note: the pinout may differ from other ESP32 boards!)

Power consumption:

  • Switched off with the switch (DC-DC 5V boost stays on): ~15uA
  • Switched on with the switch, ESP32 in deepsleep: ~15mA (consumption largely through voltage regulator)

If you want to use the board as Arduino, start here. After installation you select the board ""WeMos" WiFi&Bluethooth Battery".

The drivers can be found here: CP210x USB to UART Bridge VCP Drivers

Note: The pins on the board are directly connected to the ESP32 chip and are therefore only suitable for 3.3V signals.

Note: Despite the text label on the board, this is not an original Wemos product.
