Holybro DroneCAN RM3100 Professional Grade Compass (42cm cable length)

Description: The compact professional RM3100 magnetometer from Holybro is a top-tier solution for precise direction and orientation sensing for your drone. The model features PNI's leading magneto-inductive technology, providing an excellent signal-to-noise ratio, virtually no drift, and exceptional reading stability. With high resolution (10 nT) and ultra-low magnetic hysteresis, this compass is ideal for applications requiring the highest navigation accuracy and compensation for magnetic distortions from motors or metal components.

The device has a built-in DroneCAN output protocol, allowing for a robust and reliable connection over significant distances. Integration via the DroneCAN bus simplifies wiring and allows multiple peripheral devices to be connected via a single interface, without occupying additional serial ports on the flight controller. The 42cm cable length makes installation convenient in various quadcopter designs.

Advantages and Applications

This magnetometer ensures smooth and precise operation of the navigation system: it reduces the impact of magnetic distortions from motor coils and metal parts, increasing overall flight stability and track accuracy. The RM3100 is suitable for professional drones, research platforms, mapping, agricultural drones, and any projects where high orientation accuracy is critical.
