Hardware Assembly

The LS20031 module does not have a connector attached. In order get data from the unit, we need to attach a connector or some connecting wires. Whatever method of connection you use, remember it is important to keep the square ceramic antenna so it is pointed toward the sky. Break off 1x5 row of right angle headers to solder to the GPS receiver.

Note: You may prefer to use plain wire or M/M jumper wires like those pictured below but we will not cover this method here.

The most difficult part of the assembly process is probably keeping the right-angle header connector aligned while soldering the pins to the GPS receiver. We'll use sticky tack to hold the pins down against the board. Temporarily fasten one of the outside pins of the connector in place ensuring that all the connector pins overlap the appropriate gold-colored pads on the GPS module circuit board.

Note: You will notice the small holes (vias) around the outside of the module run under two of the pins—it is okay if these two pins of the connector make contact with the small holes as in this case both the pins and vias are connected to ground.

Once you're satisfied with the position of the connector, solder the pin at the opposite end of the connector. You can use more solder than you might normally as it will need to provide structural support in addition to electrical contact. As usual, try not to hold the soldering iron in contact for more than a few seconds. Also, make sure you don't accidentally de-solder any of the other components on the board or flick solder onto the board. When you've soldered the first pin it should look similar to this.

Next remove the temporary adhesive and ensure the pins are still aligned correctly on the pads—if they're not, apply heat to the already soldered connector and gently move the connector into alignment. Then solder the other outside pin into place.

Finally, solder the remaining three pins to their pads. With the two outside pins in place the remaining pins should stay in alignment with the pads. When you've finished your module should look something like the image below.

Now that your GPS module has a right-angle connector you can plug it directly into a breadboard. We recommend inserting the headers close to the center of the breadboard for a secure connection and stability.
