The GY-271 HMC5883L 3-axis Electronic Compass Module with original HMC5883L chip is designed for accurate low-field magnetic sensing and heading detection. This compact sensor module measures magnetic fields on three perpendicular axes (X, Y, and Z) and outputs digital data via the I2C interface, making it easy to integrate with microcontrollers such as Arduino, Raspberry Pi, and other embedded systems.
Ideal for small projects like UAV navigation, robotics, and other orientation-sensitive applications, the GY-271 module converts detected magnetic fields into differential voltage outputs for each axis. These raw data values can be processed to calculate precise heading angles or detect magnetic disturbances in the environment.
The module comes on a development board with easy-to-use connectors, simplifying integration and prototyping. It’s a reliable choice for developers working on multirotor drones, robotic navigation, and electronic compass applications.
