GY-271 HMC5883L/QMC5883L Triple Axis Compass Magnetometer Module (3V-5V)

The GY-271 Triple Axis Compass/Magnetometer Module is an essential sensor for achieving accurate directional sensing and navigation in your electronics projects. Equipped with the high-performance HMC5883L (or compatible QMC5883L) chip, it delivers reliable three-dimensional magnetic field data, allowing your Arduino, Raspberry Pi, or other microcontroller projects to easily function as an electronic compass.

✨ Key Features & Benefits

• Precise Triple Axis Sensing: Provides X, Y, and Z-axis magnetic field strength data for full-range orientation and heading detection.
• Standard IIC Communication: Utilizes the widely adopted $I^2C$ (IIC/TWI) protocol, enabling fast connection and communication with the host controller using only two signal lines.
• Wide Voltage Compatibility: Supports a 3V to 5V power supply, making it directly compatible with most mainstream microcontroller systems like Arduino UNO and Mega.
• Compact Size: The module's compact design ($13.2mm \times 14.4mm$) allows for easy integration into space-constrained applications such as drones, robotics, or wearable devices.
