A development board from Olimex based on ESP32-WROOM. With the built-in Wi-Fi, Bluetooth and Ethernet PoE interface, this board is ideal for IoT applications. The USB to serial converter makes it easy to program, also like an Arduino. The board has a micro USB connection with which it can be programmed and/or powered (micro USB cable not included). This board also supports Li-ion/Li-Po power supply and charging.

This EA version of the board comes with an external antenna.
