Wemos Lolin D1 Mini Pro V2

The WeMos D1 mini PRO is a miniature wireless 802.11 (Wifi) microcontroller development board. It turns the very popular ESP8266 wireless microcontroller module into a fully fledged development board. Programming the D1 mini pro is as simple as programming any other Arduino based microcontroller as the module includes a built in microUSB interface allowing the module to be programmed directly from the Arduino IDE (requires the ESP8266 support to be added via board manager) with no additional hardware. 

The D1 mini Pro is also designed to allow Wemos compatible shields to be plugged into the board in a similar way to the Arduino development board platform, which greatly expands its capabilities. There is already a large range of compatible shields available and these can also be purchased via our website. 

New V2.0 features: This version now includes a lithium battery charging circuit (500mA max) and header which allows the module to be powered from a 3.7V single cell lithium battery.
