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.
