Arduino GPS System

Provides a fully functional GPS receiver capable of displaying the current coordinates, heading, speed, average speed, maximum speed, date and time. Can also display the bearing, distance and ETA to a way-point for navigation.

Two versions are available: One which uses only a GPS receiver and one that uses a GPS receiver and a digital compass.

LED Shield

Provides 8 LEDs for displaying directions. Can be used as a compass or to display the course to a specific way-point or a series of way-points.

How to Make Your GPS Receiver Portable

Power

The best way to power an Arduino is by using a Minty Boost. The Minty Boost outputs power over USB at 5 volts using a step-up power transformer which is incredibly efficient. The Minty Boost also takes AA batteries which are cheap, convenient and rechargeable.

Protection

For protection, I recommend a Pelican case or Otter box. Both are strong, waterproof, transparent, and can be purchased in a number of sizes to fit your project. Neither are very expensive.
