Holybro DroneCAN RM3100 Professional Compass Module

The RM3100 offers superior signal-to-noise ratios, effectively eliminating drift and providing exceptionally precise magnetic field measurements. Its PNI magneto-inductive technology ensures high resolution and ultra-low magnetic hysteresis, crucial for professional-grade heading accuracy. This makes it highly reliable in environments with potential magnetic interference from motors or other components.

DroneCAN facilitates robust communication over long distances and reduces wiring complexity significantly. It allows multiple peripherals to connect via a single bus, freeing up serial ports on the flight controller. This architecture minimizes potential points of failure, enhances data integrity, and makes system expansion more straightforward for UAVs.

This compass module is primarily designed for flight controllers that support the DroneCAN protocol, such as those running ArduPilot or PX4 firmware. Its DroneCAN interface ensures seamless plug-and-play integration without consuming serial ports, making it ideal for advanced autonomous UAV platforms where resource optimization is critical.

For optimal performance, the RM3100 module should be mounted as far as possible from motor coils, ESCs, power cables, and any ferrous metal parts that could generate magnetic interference. Ensuring clear line-of-sight to the sky and proper orientation according to the flight controller's setup guide will maximize heading accuracy and stability.

Yes, the Holybro DroneCAN RM3100 is engineered for resilience, with an operating temperature range of -40°C to +85°C. This wide range ensures reliable performance across diverse climates, from freezing high-altitude operations to hot desert environments, making it suitable for a broad spectrum of industrial and professional UAV applications.
