The WiFly click (MIKROE-1937) by MikroElektronika—with its onboard Microchip RN-131 standalone, embedded wireless LAN module—allows you to connect your devices to 802.11 b/g wireless networks quite simply, with its preloaded firmware. The mikroBUS UART interface alone (RX, TX pins) is sufficient to establish a wireless data connection (with speeds up to 1 Mbps), and the module is controlled with simple ASCII commands (for scanning, authenticating and connecting to Wi-Fi networks). Plus, a 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. Note: 3.3V power supply only.
