GPS for Flipper Zero

A simple Flipper Zero application for NMEA 0183 serial GPS modules, such as the Adafruit Ultimate GPS Breakout.

Heavy lifting (NMEA parsing) provided by minmea.

Installation

Navigate to the FAP Build GitHub action workflow, and select the most recent run.
The FAP is built for both the dev and release channels of the official firmware. Download the artifact corresponding to your firmware version.
Extract gps_nmea.fap from the ZIP file to apps/GPIO on your Flipper Zero SD card.

This is a single-screen app, and a few interactions are provided via the hardware buttons:

Long press the up button to change the baud rate. The default baud rate is 9600, but 19200, 38400, 57600, and 115200 baud are also supported.
Long press the right button to change speed units from knots to kilometers per hour.
Press the OK button to set the backlight to always on mode. Press it again to disable.
Long press the back button to exit the app.

Connect the GPS module to power and the USART using GPIO pins 9 (3.3V), 11 (GND), 13 (TX), and 14 (RX), as appropriate.

See the tutorial video from Lab401 by RocketGod for a visual guide to the hardware setup.
