# High autonomy GPS tracker.

A custom Arduino 2 layers PCB done with [Kicad](http://kicad-pcb.org/) meant to be use with a dedicated [firmware](https://github.com/blemasle/gpstracker-firmware). The result is a high autonomy GPS tracker that can be use to track moving vehicules.

Solering this PCB requires either the use of soldering paste or fine soldering skills.
The SIM808 IC can indeed be quite hard to solder by hand because of its form factor that requires you to solder each one of its 64 pins separately instead of the usual flux and drag technique. Moreover, the shape of each pin make it very easy to solder several pins together or soldered with not enough tin to make a reliable connection.
