Features:

• Low noise, low temperature drift, high resolution car grade RM3100 electronic compass
• Advanced magnetic filtering algorithm can effectively eliminate magnetic interference and accurately measure the heading of the device
• Self-developed M4C software architecture, rapid customization and development
• DroneCan bus protocol, supports open source platforms such as PX4/ArduPilot

C-Compass

C-Compass is a high-performance industrial anti-interference magnetometer; it integrates a vehicle-grade RM3100 electronic compass and supports the DroneCAN protocol, widely used in unmanned systems such as PX4 or ArduoPilot as an external compass to eliminate magnetic field interference from internal components (cables, batteries, motors e.g.).
