ESP32 Wemos LoLin32 ESP32 The Wemos LoLin32 is a development board built around the Espressif ESP-WROOM-32 microcontroller. It claims 4MB of memory and offers WiFi and Bluetooth connectivity. The Wemos LoLin32 has the particularity to propose a connector for LiPo battery. The connector is JST XH2-2mm. It has a key that stops reverse division. Charging the battery and programming will be done using the usual micro-USB connector.

Unlike the first ESP32 development cards, this card developed by is thinner. It leaves a row of connectors on each side of the board free on the breadboard.

The WeMos LOLIN32 board is based on the ESP-WROOM-32 module and adds a LiIon/LiPo battery charging circuit, a USB to serial converter IC and a USB port. Solder the headers to the PCB and use it directly on any breadboard. The ESP8266 is great for small projects where you don’t need so many I/Os, processing power or interfaces.
