Step 2Hooking it up
Actually hooking up the unit is pretty simple. If you are using a voltage regulator, make sure to connect the ground to the negative terminals of the battery, serial port, and GPS. You can use any type of power source you want as long as you provide it within the range provided in the manufacturers manual. (GPS15L 3.3 - 5.4VDC)
The USB port outputs 5.05V normally, so that is also an option.
I originally had a broken fiber optic light that took 3 AA batteries. One AA or AAA battery is 1.5 volts. The fiber optic light had the batteries connected in series, so the actual output was 3x1.5 = 4.5volts. I originally used the fiber optic lights power source cut out and put in the Tupperware container with the GPS unit. The only difference is that there was no voltage regulator. I just hooked the grounds together and directly soldered the wires.
