Holybro DroneCAN RM3100 Compass 42cm Cable
Holybro DroneCAN RM3100 Compass 42cm Cable - Maximum Accuracy and Reliability in Any Condition
The Holybro DroneCAN RM3100 Compass with 42 cm cable is a professional-grade magnetometer designed for UAVs and autonomous vehicles. Built with advanced magneto-inductive technology, it delivers precise, drift-free heading and orientation data, even in challenging environments. Its IP66-rated enclosure protects against dust and water, ensuring reliable operation in all conditions. Perfect for demanding applications, this compass enhances navigation accuracy, reduces magnetic interference, and integrates easily via the DroneCAN protocol, making it the ultimate choice for professional pilots and engineers.

Professional-Grade Accuracy for Reliable Navigation
This professional-grade RM3100 compass/magnetometer has impeccable signal-to-noise ratios, no drift, and precise magnetic field measurements. It can provide professional-grade heading accuracy and orientation calculations for your vehicle. With this compass, your vehicle can navigate through waypoints with little magnetic disturbance due to motor coils and metal parts. You can achieve the best result by placing this module far away from motor coils and other metal parts, getting rid of one of the largest points of failure on your unmanned vehicle.
High-Resolution 3-Axis Magnetometer for Precision
This 3-axis magnetometer, based on PNI’s proprietary magneto-inductive technology, delivers high-performance resolution and repeatability. It has a very high level of resolution (10 nT) and ultra-low magnetic hysteresis, making it perfect for applications that require high heading accuracy.
DroneCAN Connectivity for Simplified, Robust Integration
With its DroneCAN output protocol, it can deliver robust and reliable connectivity over relatively large distances, and wiring is less complicated, as you can have a single bus for connecting all your DroneCAN peripherals. It also does not occupy any serial ports on the flight controller.
RM3100 module now come with a housing with IP66 rating, and software CAN termination resistance toggle.
