Digital Compass Sensor High Accuracy Electronic Heading Module for Navigation and Antenna Control Systems
Product Introduction

The FCM250B/260B is a low-cost three-dimensional electronic compass that utilizes hard and soft magnetic calibration algorithms to eliminate magnetic field interference through advanced calibration. This compass integrates a three-axis fluxgate sensor and calculates heading in real-time via a central processor, while a three-axis accelerometer provides heading compensation for tilt angles up to ±85°, ensuring high accuracy even at extreme angles.

Featuring high-precision MCU control and multiple output options, the electronic compass offers standard interfaces including RS232/RS485/TTL, with custom communication interfaces available upon request.

With its compact size, low power consumption, and robust construction, the FCM250B/260B is suitable for stable antennas, vehicles, and system integration applications. Its high shock resistance and reliability enable operation in extremely harsh environments, making it ideal for precision measurement integrated control systems.
