GPS Logging Arduino Shield

ladyada continues to produce more and more interesting Arduino shields. This new GPS logger plugs into a standard Arduino board and has support for four different GPS receiver modules. On the backside of the board is an SD card slot where it stores the coordinates in a text file. The total runtime can vary from five hours to twenty depending on how you choose to power the device and how you use the device. How often you read the device and whether you maintain the GPS lock will affect the power consumption. Like all of ladyada’s projects, you’ll find a great construction guide and example code on her site.
