GPS Shield Wiring it up

Even after soldering all the parts, there is some 'fly wiring' that is required to get the shield to do what you want. The reason it was designed that way is so that people with unique requirements could easily customize how they want the shield. However, we will cover the most common cases.


There are two parts of the shield: the GPS module interface and the SD card interface. The SD card must be connected to the Arduino digital pins 13, 12, 11, and 10 for it to work and so those pins are 'taken'. The GPS module interface does not have to be connected to any -particular- pin so they are left free for you to jumper with common wire.. The GPS module interface is as follows:

The only really important pins are PWR, TX and RX. Some modules work even when RX is not connected to anything (floating) but many act kind of strange so I suggest always connecting it up.

Make your wires

Cut three pieces of wire, two about 1" long and one 2" long.

Solder the two shorter ones to RX and TX. Solder the longer one to PWR.

Now continue to the next step, which is testing the GPS module by connecting it to your computer
