Key Features

RM3100 Magneto-Inductive Technology

Delivers 23× better resolution and 33× lower noise than conventional Hall-effect magnetometers, with inherent immunity to electromagnetic interference from motors, ESCs, and high-current power electronics.

DroneCAN Plug-and-Play

Communicates entirely over the standard CAN bus, integrating seamlessly with ArduPilot and PX4 flight stacks alongside existing GPS modules and flight controllers with no additional wiring complexity.

Redundancy-First Design

Purpose-built as a secondary or tertiary sensor node for large multirotors, octocopters, VTOL, and fixed-wing aircraft where sensor diversity is critical and single-sensor failure is not an option.

Zero Drift, Zero Hysteresis

The RM3100 delivers stable, drift-free measurements over time and temperature without requiring recalibration — ideal for long-range missions and long-duration deployments where reliability is paramount.
