2. Soldering the headers

3. Plugging the board in

Once you have soldered the headers your

board is ready to be placed into the desired

mikroBUS™ socket. Make sure to align the

cut in the lower-right part of the board with

the markings on the silkscreen at the

mikroBUS™ socket. If all the

pins are aligned correctly,

push the board all the way

into the socket.

Turn the board upward again. Make sure

to align the headers so that they are

perpendicular to the board, then solder the

pins carefully.

Turn the board upside down so that

the bottom side is facing you upwards.

Place shorter pins of the header into the

appropriate soldering pads.

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.

4. Essential features

The RN-131 module’s 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, UDP, DNS, ARP, ICMP, TCP, HTTP client, and FTP client. Data rates of up to 1 Mbps are achievable through UART. It contains both an onboard chip antenna and a connector for an external antenna. .

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. The module includes preloaded firmware which simplifies integration. The mikroBUS™ UART interface alone (RX, TX pins) is sufficient to establish a wireless data connection. Additional functionality is provided by RST, WAKE, RTSb and CTSb pins. The board uses a 3.3V power supply only.
