Connections

Connect your GPS module VCC and GND to corresponding VCC and GND on your Marauder. Use the following table as a reference to make the UART connection between your Marauder and GPS module:

Marauder Hardware GPS TX GPS RX
OG Marauder IO04 IO13
Marauder v6 IO04 IO13
Marauder Kit IO04 IO13
Marauder Mini IO21 IO22
Flipper Zero WiFi Dev Board IO09 IO21
WiFi Dev Board Pro IO21 IO17

Use a piece of strong double sided tape like from 3M to adhere the GPS module and antenna to a spot on the Marauder PCB/Enclosure.

Verifying Successful Installation

You will know if you've successfully installed the GPS module if you see a "GPS Data" menu item on the "Device" menu of Marauder. You will also see a red or green satellite icon on the far left side of your status bar. If you have not properly installed the GPS module or you used an incompatible GPS module, you will not see these two items.

Antenna

The following options are available when attaching an antenna to your GPS module. Since most GPS modules feature an IPX socket, you can use ceramic antennae or SMA antennae with a pigtail adapter. Your options are not limited to this list but these are good examples and have undergone successful testing:

Ceramic

SMA

The following enclosures can be used for the Marauder v6 when mounting your GPS antenna. If you select a model that requires brass inserts, use these.
