LOLIN32 with ESP32, WiFi, Bluetooth / BLE

The LOLIN32 board is based on the ESP-WROOM-32 module and adds a LiIon/LiPo battery charging circuit, an USB to serial converter IC and an 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. Espressif listened to their customers and put a lot more into the new ESP32 WiFi-SoC:
