This is an easy make, and should only take a few minutes. Either follow the instructions below or watch the video.

Let’s start with the two headers. Instead of mounting the board in a vice as usual, plug the two headers into your Arduino, and put the board on top. This makes sure that the headers are lined up and will plug in nicely then solder them. This method obviously doesn’t work so well with the female headers we now ship with. For those, I like to fill in one holes with solder, then heat it while pushing the header through and aligning them to the surface of the board. Whatever method works for you is fine! |

Strip the wire, tin the ends, and solder one end into the “DIG” hole. Don’t solder the other end – just make sure that it plugs into the ‘duino RX hole nicely. You will need to unplug it when you are reprogramming the ‘duino, or else the radio will interfere with the programming. |
 |
Now add the radio. The pins on the board are slightly offset and will hold the radio firmly while you are soldering. You may need to bend them in slightly with your thumbnail. Line the radio up so that the “ant” pin is closest to the “ANT” hole on the main PCB. Solder it in place. |
 |
Now for the Helical antenna. You will need to bend the one side of the helical antenna so that it inserts vertically. Using two pairs of pliers is the simplest. Once that is done, insert it and solder. Make sure it does not touch the radio receiver. |
All done!
