2. Soldering the headers Before using your click board , make sure to solder 1x8 male headers to both left and right side of the board. Two 1x8 male headers are included with the board in the package. 1 WiFly click 2 3 4. Essential features The RN-131 modules firmware makes it easy to set up, scan for access points, associate, authenticate and connect the WiFly click to a Wi-Fi network. The module is controlled with simple ASCII commands. It has a multitude of networking applications built in: DHCP, Turn the board upside down so that Turn the board upward again. Make sure UDP, DNS, ARP, ICMP, TCP, HTTP client, and the bottom side is facing you upwards. to align the headers so that they are FTP client. Data rates of up to 1 Mbps are achievable through UART. It contains both an Place shorter pins of the header into the perpendicular to the board, then solder the onboard chip antenna and a connector for an appropriate soldering pads. pins carefully. external antenna 1. Introduction 3. Plugging the board in WiFly click carries RN-131, a standalone, embedded wireless LAN module. It allows click Once you have soldered the headers your you to connect your devices to 802.11 b/g board is ready to be placed into the desired wireless networks. The module includes BOARD mikroBUS socket. Make sure to align the preloaded firmware which simplifies www.mikroe.com cut in the lower-right part of the board with integration. The mikroBUS UART interface the markings on the silkscreen at the alone (RX, TX pins) is sufficient to establish mikroBUS socket. If all the a wireless data connection. Additional WiFly click manual ver 1.00 pins are aligned correctly, functionality is provided by RST, WAKE, RTSb and CTSb pins. The board uses a 3.3V power push the board all the way supply only. into the socket. 01000000819768. Code examples 5.
