GY-273 HMC5883L 3-Axis Digital Compass Magnetometer Sensor

The HMC5883L 3-Axis Digital Compass Magnetometer Sensor Module is a compact and versatile solution for precise magnetic field measurements along three axes. Ideal for navigation systems, robotics, and consumer electronics, this module delivers accurate heading information with a 1° to 2° accuracy.

It features the HMC5883L IC from Honeywell, which uses Anisotropic Magnetoresistive (AMR) technology for high sensitivity and reliability. The module supports I2C communication, making it easy to integrate with microcontrollers such as Arduino. An on-board voltage regulator allows operation with supply voltages from 3.3V to 6V, and on-board pull-up resistors simplify I2C connections.

Features :

• Triple-axis magnetometer for X, Y, Z magnetic field measurements
• Digital output via I2C interface
• On-board voltage regulator (3.3V to 6V input)
• On-board I2C pull-up resistors
• Data ready interrupt pin (DRDY)
• High accuracy: 1° to 2° heading accuracy
• 12-bit ADC for precise measurements
• Low power consumption
