evive has a dedicated WiFi headers, which just requires you to connect the ESP8266 WiFi module. Communication between evive and the WiFi module occur via serial port 3.
ESP8266 WiFi Module is a self-contained SOC with integrated TCP/IP protocol stack that can give any microcontroller access to your WiFi network. The ESP8266 is capable of either hosting an application or offloading all Wi-Fi networking functions from another application processor. Each ESP8266 module comes pre-programmed with an AT command set firmware, meaning, you can simply hook this up to your evive and get about as much WiFi-ability as a WiFi Shield offers.
