1 Overview
The “WiFly” radio module is a complete stand alone embedded wireless LAN access device. The
device has on board TCP/IP stack and applications. Requiring only 4 pins (POWER, TX, RX, GND) to
design in. Once initial configuration is set, the radio can automatically access the WiFi network and
send/receive serial data over UART.
