WiFi uses industrial-grade chips ESP8266, ESP-13 module with a metal shield, anti-jamming.
Standard pin-compatible Arduino Uno, Mega2560 and other control board, Arduino UNO and connected by a voltage converter chip, so 3.3V and 5V compatible.
With dual serial ports DIP switch is controlled such that the expansion board can be used alone as an expansion board Arduino Uno used either as an expansion board ESP8266 use.
Real serial port WiFi, Arduino program without any configuration; configure WiFi parameters and serial port parameters based Web Server.
ESP8266 can be used as stand-alone development board, download the official AT commands firmware, NodeMCU open source firmware. Can be used as stand-alone expansion board Arduino Uno use, pin all the leads.
