This complete module is built upon the same technology as the ET-301, but includes on-board voltage regulation, LED status indicator, battery backed RAM, and a built-in patch antenna! 6-pin interface cable included.

The SiRF 20 channels GPS receiver module is ideal to add features to your autonomous mobile robot and helps you to create geo-localised applications.

Note: The cables we have been getting with these have a gray wire on alternating sides of the connector. Check the datasheet for correct pinout. Don't pay attention to which wire is gray, reference the pinout of the actual module.
