MATEK GNSS & COMPASS M9N-5883

• M9N-5883 uses multi-constellation GNSS powered by u-blox NEO-M9N , NEO-M9N is a concurrent GNSS receiver which can receive and track multiple GNSS systems. Owing to the multi-band RF front-end architecture all four major GNSS constellations, GPS,Galileo, GLONASS and BeiDou can be received concurrently.
• More details about the NEO-M9N, pls check out u-blox NEO-M9N page

• M9N-5883  G  to Flight controller GND

• Compass Alignment(Arrow forward and flat mounting):
  INAV/BetaFLight: CW 270° Flip when flight controller arrow is facing forward also.
  Ardupilot/Mission Planner: Rotation None.
• Protocol: Ublox or NMEA
• Make sure to have compass/magnetometer 10cm away from power lines/ESC/motors/iron based material
• The scratches on ceramic antenna are the result of tuning the antenna.

• Betaflight doesn’t support NEO-M9N over UBLOX protocol,  Pls select NMEA protocol & Auto Baud.

• INAV2.5 ublox/ublox7/NMEA all don’t support NEO-M9N.   M9N is supported by INAV2.6 ublox or ublox7 protocol(both run at 5Hz)

• NEO-M9N is supported by ArduPilot 4.1 (latest)

• HD cameras(Gopro, Split, Tarsier, etc) could interfere GPS signal, try turning off HD camera before GPS 3D fix
• The NEO-M9N provides the ability to reset the receiver. Bridging “RST” pad to Ground for at least 100 ms will trigger a cold start. RESET will delete all information and trigger a cold start. It should only be used as a recovery option.
