Matek GPS & Compass Module M9N-5883

Description

M9N-5883 GNSS Receiver with Multi-Constellation Tracking and Integrated Compass

The M9N-5883 GNSS receiver is a high-performance module powered by the NEO-M9N chip, capable of tracking multiple GNSS systems concurrently, including GPS, Galileo, GLONASS, and BeiDou. Equipped with a QMC5883L magnetic compass and a 25x25x4mm patch antenna, this module ensures accurate positioning and orientation for your UAV or robotics projects.

The M9N-5883 is designed for seamless integration with flight controllers, featuring a JST-GH-6P connector, UART interface for GNSS, and I2C interface for the compass. Its compact design and low power consumption make it an ideal choice for various applications.

Compass Alignment:

• INAV/BetaFlight:
  • Arrow forward: Set CW 270° Flip when flight controller arrow is forward.
  • Arrow backward: Set CW 90° Flip when flight controller arrow is forward.
• Ardupilot/Mission Planner:Rotation None.

Additional Notes:

• Ensure compass/magnetometer is mounted at least 10cm away from power lines, ESCs, motors, or any iron-based material.
• Compatible with INAV 5.0.0, Betaflight 4.3.0, ArduPilot 4.3 or newer.
• The NEO-M9N series does not have built-in dataflash; settings revert to default after power loss.
• Use the UBX protocol for bidirectional communication; flight controller firmware can adjust GPS settings automatically.
• Timepulse alignment with UTC may take up to 12.5 minutes after a cold start.
• For troubleshooting GPS issues, refer to the troubleshooting guide.
