MicoAir MG-902 GNSS GPS & Compass Module

The MicoAir MG-902 is a compact GNSS module equipped with an integrated compass, built to deliver accurate positioning and heading data for FPV long-range builds, autonomous rigs, and cinematic drones. Whether you are configuring basic GPS Rescue in Betaflight or programming complex waypoint missions in INAV and ArduPilot, this receiver provides the essential telemetry required for precise navigation.

Key features

• Concurrent multi-constellation GNSS reception for rapid satellite acquisition and strong signal retention in challenging environments.
• Integrated hardware compass for accurate heading lock and stable return-to-home alignment.
• Compact footprint designed to mount cleanly onto standard FPV frames and custom TPU enclosures.
• Straightforward wiring scheme requiring a standard UART connection for GPS data and an I2C bus (SCL/SDA) for the compass.

When installing the MG-902, ensure it is mounted well away from high-current ESC power leads, motors, and VTX antennas to minimise electromagnetic interference with the onboard magnetometer.
