WeMos D1 WiFi UNO - ESP8266

WeMos- D1 WiFi UNO - ESP8266 Development Board is programmable via Arduino IDE. This is an ESP8266 based WiFi enabled microprocessor unit on a Arduino-UNO footprint. That means the board looks and works (in most cases) like an UNO. Several shields, sensors and output devices that are manufactured for the Arduino platform will work on the WeMos-D1R2 with the added advantage of built-in WiFi.
