Soldering the headers
- Before using your click board™, make sure to solder 1×8 male headers to both left and right side of the board. Two 1×8 male headers are included with the board in the package.
- Turn the board upside down so that bottom side is facing you upwards. Place shorter parts of the header pins in both soldering pad locations.
- Turn the board upward again. Make sure to align the headers so that they are perpendicular to the board, then solder the pins carefully.
Plugging the board in
Once you have soldered the headers your board is ready to be placed into desired micro BUS™ socket. Make sure to align the cut in the lower-right part of the board with the markings on the silkscreen at the micro BUS™ socket. If all of the pins are aligned correctly, push the board all the way into the socket.
