BetaFlight

BetaFlight has basic GNSS support (primarily for OSD and RTH on fixed wing).

1. Wiring

• Connect TX/RX to a free UART

• Magnetometer is typically unused unless you’re running iNav or special builds

2. Enable GPS Feature

Connect via USB and use the CLI:

feature GPS
set gps_provider = UBLOX
set gps_baudrate = 115200
save

3. Verify in OSD

Enable GPS coordinates, sats, and speed in the OSD tab.
