Adafruit Ultimate GPS Logger Shield - Includes GPS Module info
Adafruit Ultimate GPS Logger Shield - Includes GPS Module 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, or maybe a music player that changes tunes depending on where you are in the city.
If your project is going to be inside an enclosure, you'll love Adafruit Ultimate GPS Logger Shield - Includes GPS Module as it has external antenna support. Simply connect an external active GPS antenna via a uFL/SMA cable to the shield and the module will automatically switch over to use the antenna. You can then place the antenna wherever you wish.
