GY-271 QMC5883L Magnetic Sensor Module – 3-Axis Electronic Compass with I2C Output

The GY-271 QMC5883L Magnetic Sensor Module is a compact 3-axis digital compass designed for accurate magnetic field sensing in embedded systems, robotics, and navigation-based applications. Utilizing the QMC5883L chip, this module can precisely detect magnetic field strength and direction in three axes, making it ideal for heading detection and orientation control.

This module operates with a 3–5V DC input and communicates through the standard I2C interface, which makes it easy to integrate with popular platforms like Arduino, Raspberry Pi, ESP32, and other microcontrollers. Although some boards are labeled HMC5883L, they may include a QMC5883L chip instead. The QMC5883L offers similar capabilities but requires a different library due to its register differences.

Whether you’re building a drone, autonomous robot, or a navigation-enabled IoT device, this sensor is a great choice for accurate magnetic field monitoring with minimal footprint and low power consumption.
