WeMos D1 ESP8266 WiFi Board (UNO Based)
The ESP8266 D1 R1 WiFi board utilizes the ESP8266 WiFi enabled processor, and puts it onto an Arduino Uno board footprint. It provides a way to work with the ESP8266 in a familiar setup and does not require a breadboard in order to make interconnections since it has the typical on-board female headers. It will also work with some Uno shields that have compatible I/O pin-outs.
