GPS Backpack

by nsayer.

2 layer board of 3.15x1.40 inches (80.04x35.59 mm).

A battery powered GPS reverse geocache backpack.

This version corrects a minor problem in the prototype that prevents programming with the LCD attached. It should be fully functional.

Power draw from two 1.5 volt primary cells is 150 mA when operating, 1 mA standby. With AA alkaline batteries, that should be a combination of 10 hours operating or 90 days standby.

Firmware is available from http://github.com/nsayer/GPS_Pack

The GPS module is the Adafruit Ultimate GPS module.
