Overview
WIFI Shield REV2 supports IEEE 802.11b/g/n wireless protocol standard and serial output, which integrates TCP / IP protocol stack internally. It is specifically designed for Arduino boards including Arduino UNO, MEGA and Leonardo, and it supports 3.3V or 5V operation level so it can work with more Arduino-compatible boards.
