CUAV C-Compass RM3100 High-precision Sensor

The CUAV C-Compass RM3100 High-Precision Sensor is an CUAV external magnetometer module engineered for professional UAV and robotics applications. It integrates an automotive-grade PNI RM3100 magneto-inductive sensor and an STM32F4 processor, providing extremely low noise and robust interference resistance. this module is “high-performance, industrial-grade” compassing solution, and it delivers a stable heading reference with far better resolution and lower noise than typical Hall-effect compasses.

Features:

• High-performance, industrial-grade interference resistance.
• Proprietary M4C software architecture.
• Supports DroneCAN protocol.
• Compatible with ArduPilot and PX4 platforms.

Specifications:

Applications:

• Precision heading reference for UAVs (multi-rotors, fixed-wing, VTOL) running PX4 or ArduPilot.
• External compass for autonomous drones and robotic vehicles (surveying, mapping, inspection, delivery) where EMI is high.
• Industrial and commercial UAVs requiring magnetometer redundancy and high‐accuracy navigation.
• Ground robots and rovers needing robust orientation data in magnetically noisy environments.
• Research and academic platforms in aerospace or geophysics where precise magnetic sensing is critical.

Package Include:

• 1x CUAV C-Compass RM3100 High-Precision Sensor module (droneCAN magnetometer).
• 1x 35 cm DroneCAN cable (4-pin JST-GH) for connecting to autopilot CAN port.
• 2x M3 double-sided foam adhesive tape pads (for mounting).
