ESP8266 WiFi Shield for Arduino Expansion Board diaphragm (according to the principle of1. Standard pin interface to achieve full compatibility with the pitch for Arduino Uno, Mega, and so on. (Unless the standard size for Arduino, such as Nano, Mini) 2. 3. 3V power supply using advanced chip (with the official expansion board power chip CC3000 same), so 3. 3V for Arduino board provided more accurate, so ESP8266 as official cc3000 chip work as normal, there is no gap. 3. It leads to a WiFi module power supply service interface to
