This Adafruit GPS shield turns your Arduino into a GPS location datalogger! (GPS & SDCard not included)
The Adafruit GPS shield kit has bring easy GPS interfacing and data-logging capability to your Arduino Create your own geo-locative project!
Please note that this shield does not come with a GPS module (sold separately), or SD memory card.
Add a supported GPS module, and load up any of the example Arduino sketches for parsing GPS data (NMEA sentences), logging to a FAT16-formatted SD flash memory card and storing analog sensor data along with precise location, date and time in CSV format.
The shield is designed specifically for use with the popular and robust EM-406a GPS module. Other compatible modules include the Tyco A1035D, EB-85A or Lassen IQ units.
The Arduino SD-card library is rather bulky, requiring 12K of flash and more than 1/2 K of RAM for buffering SD card memory blocks. The examples work fine on ATmega168-based Arduino, but '328 variants are strongly recommended (which are also pretty much standard now).
Based on ~70mA consumption @ 5V, the run-time is approximately 3 hours with a 9V battery and up to 12 hours using a MintyBoost, assuming no power-saving features are enabled.
