The GCM380/GCM385-N is a 3D electronic compass that balances high performance with cost-effectiveness. It utilizes our proprietary, patented calibration technology, ensuring a streamlined and efficient setup process. Equipped with a built-in high-precision accelerometer for tilt compensation, the device delivers stable and reliable heading data across a full 360°roll range (±180°). It maintains exceptional measurement accuracy even in the presence of fixed magnetic interference and supports multiple serial communication interfaces—including RS232, RS485, and TTL—facilitating seamless integration into diverse systems.

The unit integrates a 3-axis magnetometer and a 3-axis accelerometer, offering high resolution and robust resistance to environmental noise. It combines stable, reliable performance with a compact form factor and low power consumption, making it ideal for handheld devices, mobile platforms, antenna orientation systems, automotive equipment, and various system integration projects. Customers can choose between a fully enclosed finished product or a standalone circuit board module, allowing for flexible adaptation to specific application requirements.
