iNav

iNav supports u-blox GPS via UART and magnetometers via I²C.

1. Wiring

  • Connect TX/RX to any available UART

  • SDA/SCL go to the default I²C bus

2. CLI Configuration

Use the CLI to enable GPS and magnetometer:

feature GPS
feature MAG
set gps_baudrate = 115200
set gps_provider = UBLOX
save

Then go to the Configurator:

  • Run GPS setup

  • Run Mag calibration

Tip: Use a serial inverter (or softserial) on F4 boards if UARTs are limited.
