The GPS has a power LED labeled "GPS" on the board. The GPS is always powered when the ESP32 is powered. The GPS LED will blink when it finds satellites.

The GPS Antenna connector is next to the GPS module itself, labeled in the image below. You will need an antenna with a U.FL or IPEX connector. When connecting an antenna, disconnect the board from power first to avoid a short circuit.

The GPS Module can be used for Wardriving through Marauder firmware. Read more about wardriving from the Marauder wiki here. Wardriving requires a MicroSD card to save data.

The GPS Module will need up to 3 minutes to find a proper fix. Once found, the GPS LED should blink, and the GPS data will show in the Marauder app. You can view the GPS data in Marauder by clicking on "GPS Data > Stream"

If the GPS LED does not start to blink after a few minutes, you may need to move either to a window or outside with an unobstructed view of the sky for your GPS antenna to find satellites.
