Matek System GNSS & Compass GPS M9N-5883

Matek System GNSS & Compass GPS M9N-5883

The Matek System M9N-5883 GNSS & Compass GPS uses multi-constellation GNSS powered by u-Blox NEO-M9N, and the NEO-M9N is a concurrent GNSS receiver that 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.


  • GNSS u-Blox NEO-M9N (GPS, GLONASS, Galileo, and BeiDou)
  • Magnetic Compass QMC5883L
  • Patch antenna 25*25*4mm
  • Input voltage range: 4~6V (5V pad/pin)
  • Power consumption: 50mA
  • UART baud rate: 38400 default
  • Operating Temperatures: -20~80 °C
  • UART(TX, RX) interface for GNSS NEO-M9N
  • I2C(DA, CL) interface for Compass QMC5883L
  • JST-GH-6P connector
  • 3.3V Power LED, Red
  • GNSS PPS LED, Green, blinking(1Hz) when GNSS has 3D fixed
  • 32mm*32mm*10mm
  • 14.5g


  • 1 x M9N-5883
  • 1 x JST-GH-6P to JST-GH-6P 20cm silicon wire

Wiring and Settings

  • M9N-5883 5V to Flight controller 4~6V
  • M9N-5883 RX to Flight controller UART_TX
  • M9N-5883 TX to Flight controller UART_RX
  • M9N-5883 CL to Flight controller I2C_SCL
  • M9N-5883 DA to Flight controller I2C_SDA
  • 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 NEMA
  • Make sure to have compass/magnetometer 10cm away from power lines/ESC/motors/iron-based material
  • The scratches on the ceramic antenna are the result of tuning the antenna.
  • u-center Windows


  • NEO-M9N is supported by ArduPilot 4.1 (latest)
  • INAV2.5 ublox/ublox7/NEMA all don’t support NEO-M9N.   M9N is supported by INAV2.6 ublox or ublox7 protocol(both run at 5Hz)
  • Betaflight UBLOX protocol doesn’t support NEO-M9N,  Pls select NEMA protocol & Auto Baud.
  • 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.
