Feature Highlights: 1. Industrial-Grade Precision for Everyday Use – Originally built for navigation fields like land/ocean mapping and robotics, the RM3100 now brings the same professional accuracy to consumer products. 2. High-Accuracy Geomagnetic Sensing – Measures the Earth’s magnetic field with an accuracy of less than 10nT (under 0.1% of the total field), delivering reliable, smooth motion tracking. 3. Superior Performance – Offers over 20 times better performance compared to standard MEMS or Hall-effect sensors, with 23× higher resolution and 27× lower noise. 4. Advanced Coil-Sensor Design – Features three latest-generation coil-type magnetic sensors and an ASIC driver chip, optimized for gain, resolution, and power efficiency. 5. Flexible Connectivity – Equipped with SPI and dual interfaces for easy integration and versatile application setups. Product Details: The RM3100 is a triple-axis geomagnetic sensor module that provides stable, industrial-grade azimuth measurement. It ensures precise heading data for a wide range of uses—from console motion tracking to navigation systems—thanks to Navigation’s proprietary technology. The module is built on a durable PCB and supports plug-and-play compatibility in various electronic projects.
