HMC5883L GY-273 Pre-Soldered 3-Axis Magnetometer Compass Module for Arduino, Raspberry Pi & ESP32

GY-273 HMC5883L 3-axis magnetometer compass module is a digital heading and orientation sensor that measures the Earth's magnetic field on X, Y, and Z axes, enabling electronic compass, tilt-compensated navigation, and motion-aware projects. Built around the HMC5883L, this 3-axis magnetometer communicates over I2C for easy integration with Arduino, Raspberry Pi, ESP32, and other microcontroller or SBC platforms. It is well suited for robotics, drones, wearable devices, DIY navigation tools, and prototyping where accurate compass direction, yaw sensing, and magnetic field detection are needed reliably.
