The WeMos D1 mini Lite is a miniature wireless 802.11 (Wifi) microcontroller development board. It turns the very popular ESP8285 wireless microcontroller into a fully fledged development board. Programming the D1 mini lite 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 ESP8285 support to be added via board manager) with no additional hardware.
