WiFly click

WiFly click carries RN-131, a standalone, embedded wireless LAN module. It allows you to connect your devices to 802.11 b/g wireless networks. Preloaded firmware simplifies integration. The mikroBUS UART interface alone (RX, TX pins) is sufficient to establish a wireless data connection (with speeds up to 1 Mbps); the module is controlled with simple ASCII commands (for scanning, authenticating and connecting to Wi-Fi networks). Multitude of networking applications are built in: DHCP, UDP, DNS, ARP, ICMP, TCP, HTTP client, and FTP client. Additional functionality is provided by RST, WAKE, RTSb and CTSb pins. 3.3V power supply only.
