Honeywell HMC5883L 3-Axis Magnetometer Sensor

The Honeywell HMC5883L 3-Axis Magnetometer Sensor is a breakout board module integrating a digital 3-axis compass with on-board voltage regulation and filtering capacitors. It features a measuring range of ±1.3 to ±8 Gauss, low current consumption, and a 16-bit digital output via a standard I2C interface. The module operates at 3.3–5 V and has compact dimensions of approximately 16 × 18 mm, making it suitable for embedded systems. It is designed for applications in navigation, robotics, drones, and electronic compasses, providing precise heading and orientation data in a small form factor.
