With the GPS Shield you can add GPS functionality to your Arduino.
There have been a number of really cool Arduino projects using GPS. One of our favourite is the "Reverse Geocache Puzzle" where you have to bring the box to a specific location before it opens. Clever! To best design projects like this, you'll need to interface your Arduino to a GPS unit. SparkFun has designed this nice shield to make it quite convenient!
Adding GPS to your Arduino has never been easier. The multiple GPS receivers attach easily to the shield, and with the example sketch, you will be able to locate your exact position within a few meters. GPS also gives you amazingly accurate time! A GPS quickstart guide is available for this product.
With the GPS Shield you can add GPS functionality to your Arduino. A connector for the popular EM-406 GPS receiver is populated on the board, and footprints for EM-408 and EB-85A/FV-M8 connectors are also made available (connectors are not soldered on or included and can be found below in the related items). The regular GPS pins (RX, TX, PPS, etc.) are also broken out to a 10-pin 0.1" pitch header, and a small prototyping area is also provided.
The DLINE/UART switch switches the GPS module's input/output between Arduino's standard TX/RX pins or any digital pins on the Arduino (default setting uses pins 3 and 2 connected to TX and RX, respectively). The regular GPS pins (RX, TX, PPS, etc.) are broken out to a 10-pin 0.1" pitch header, and a small prototyping area is also provided. An ON/OFF switch is included which controls power to the GPS module. Additionally, the Arduino reset switch is also brought out.
Note: The DLINE/UART switch must be set to DLINE in order to upload code through the Arduino IDE.
The shield also includes the footprint for a 12mm coin cell battery holder to provide battery backup to the optional EB-85A GPS module.
Note: GPS modules are not included with the GPS Shield, and only the EM-406 connector is populated. Headers are also not installed, we recommend the 6 and 8-pin stackable headers.
