ESP32 CP2102 WiFi Bluetooth Development Board

Description
The Wemos LoLin32 is a development board built around the Espressif ESP-WROOM-32 microcontroller. It boasts 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 XH2-2.54mm. It has a key that prevents reverse polarity. Charging the battery and programming will be done using the usual micro-USB connector.
Unlike the first ESP32 development boards, this board developed by Wemos.cc is narrower. It leaves a row of connectors on each side of the board free on the breadboard.
