The Adafruit LIS3MDL is a triple-axis magnetometer (compass) breakout from ST, with selectable measurement ranges from ±4 gauss (±400 µT) up to ±16 gauss (±1600 µT). It's ideal for detecting magnetic north, measuring magnetic fields, or pairing with an accelerometer/gyroscope like the LSM6DSOX to create a full 9-DoF inertial measurement unit.

The breakout board includes voltage regulation and level shifting for compatibility with both 3.3V and 5V microcontrollers. STEMMA QT / Qwiic connectors provide solderless I2C connections, and the sensor also supports SPI. Arduino and CircuitPython/Python libraries are available for quick setup.

Key Features

• Selectable Range – ±4, ±8, ±12, or ±16 gauss full-scale measurement range
