This is a retired product, but fear not as there is a newer, better version available: RTL-10709
Description: This is the same product as the GPS Shield, but also includes an EM406 GPS receiver and headers. The difference is, this version comes in fancy clamshell packaging meant for our distributors. Regular customers are welcome to order, but we want to limit the amount of extra packaging finding its way into the trash heap. A GPS quickstart guide and a GPS Shield Assembly Guide are available for this product.
Adding GPS to your Arduino has never been easier. The EM406 plugs easily onto the shield, and with the example sketch, you will be able to locate your exact position within a few meters. Here's where we are. GPS also gives you amazingly accurate time!
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 protoyping 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.
