MATEKSYS M9N-5883 GNSS & Compass GPS Module, u-blox NEO-M9N + QMC5883L, JST-GH-6P

Overview

The MATEKSYS M9N-5883 GNSS & Compass GPS module is a multi-constellation GNSS receiver based on u-blox NEO-M9N, combined with a QMC5883L magnetic compass. With a multi-band RF front-end architecture, it can receive GPS, Galileo, GLONASS, and BeiDou concurrently.

Key Features

• GNSS: u-blox NEO-M9N concurrent receiver (GPS, GLONASS, Galileo, BeiDou)
• Magnetic compass: QMC5883L
• Interfaces: UART (TX, RX) for GNSS; I2C (DA, CL) for compass
• JST-GH-6P connector
• Status LEDs: 3.3V power LED (Red); GNSS PPS LED (Green), blinking (1Hz) when GNSS has 3D fixed
• Receiver reset: bridging “RST” pad to Ground for at least 100 ms triggers a cold start (recovery option)

Specifications

What’s Included

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

Wiring and Settings

• M9N-5883 5V to Flight controller 4~5.5V
• 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

Tips and Notes

• Compass Alignment (flat mounting): Tilting the magnetometer is strongly discouraged!
  • INAV/Betaflight: compass Arrow forward, set CW 270° Flip when flight controller arrow is facing forward.
  • INAV/Betaflight: compass Arrow backward, set CW 90° Flip when flight controller arrow is facing forward.
  • ArduPilot/Mission Planner: Rotation None.
• Keep the compass/magnetometer 10cm away from power lines/ESC/motors/iron based material.
• INAV 5.0.0, Betaflight 4.3.0, ArduPilot 4.3 or newer is required.
• NEO-M9N, MAX-M10S, SAM-M10Q series don’t have dataflash built in; once GNSS is powered off and the supercapacitor runs out, settings return to default.
• UBX protocol is bidirectional; flight controller firmware can change settings on GPS via UBX protocol (no need to set GNSS module parameters in u-center).
• From GNSS FW3.01: timepulse is aligned with UTC time; time is valid only after the leap second is downloaded (can take up to 12.5 min). PPS LED may not blink immediately after 3D fix.
• Reset: bridging “RST” pad to Ground for at least 100 ms triggers a cold start. RESET deletes all information and triggers a cold start; use only as a recovery option if wiring/setup are correct but the controller can’t detect the GNSS module.
• Scratches on the ceramic antenna are the result of tuning the antenna.

Details

MATEKSYS GNSS M9N-5883 combines a u-blox NEO-M9N receiver and QMC5883L compass with UART and I2C connections via a JST-GH 6-pin port.

MATEKSYS M9N-5883 combines a u-blox NEO-M9N GNSS receiver and 5883 compass on a 32mm board with TAOGLAS patch antenna and JST-GH 6-pin connectors.

The MATEKSYS M9N-5883 GNSS and compass module uses a compact board layout with JST connectors for straightforward GPS and I2C wiring.
