Adafruit Ultimate GPS Logger Shield v1
This is the Adafruit GPS shield kit that comes with an Ultimate GPS module. This GPS shield works great with either UNO or Leonardo Arduinos and is designed to log data to an SD card.
Or you can leave the SD card out and use the GPS for a geocaching project. Each order comes with one assembled and tested shield, a stick of 2.5mm male header and a 12mm coin cell
