Brand new and better than ever, we've replaced our Adafruit GPS shield kit with this assembled shield 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, or maybe a music player that changes tunes depending on where you are in the city.
The shield is built around the MTK3333 chipset, a no-nonsense, high-quality GPS+GLONASS module that can track up to 33 satellites on 99 channels, has an excellent high-sensitivity receiver (-165 dB tracking!), and a built-in antenna. It can do up to 10 location updates a second for high speed, high sensitivity logging or tracking. Power usage is incredibly low, only 30 mA during navigation.
The MTK3333-based module has external antenna functionality. The module has a standard ceramic patch antenna that gives it -165 dB sensitivity, but when you want to have a bigger antenna, you can snap on any 3V active GPS antenna via the uFL connector. The module will automatically detect the active antenna and switch over! Most GPS antennas use SMA connectors so you may want to pick up one of our uFL to SMA adapters.
Each order comes with one assembled and tested shield, a stick of 0.1" male header, and a 12mm coin cell. Some light soldering is required to attach the header to the shield in order to plug it into your Arduino. if you want to stack a shield on top, be sure to pick up a set of stacking headers to use instead. MicroSD card not included either, but we do stock them in the shop!
We think this is the Ultimate GPS shield and we also think you'll agree! For more details, tutorials, and example code check out our comprehensive tutorial.
