Adafruit Triple-axis Magnetometer - LIS2MDL - STEMMA QT / Qwiic

Sense magnetic fields with this compact Adafruit Triple-axis Magnetometer based on the LIS2MDL sensor. It detects magnetic north and measures magnetic fields in real-time using either I2C or SPI interfaces. Ideal for creating 9-DoF inertial measurement units when paired with accelerometers and gyroscopes.

This sensor supports a ±50 gauss magnetic range, 16-bit data output, and up to 150 Hz update rate. It works with 3.3V or 5V logic and features STEMMA QT / Qwiic connectors for easy plug-and-play connectivity with compatible microcontrollers. Assembly includes 0.1" headers for breadboard use and 2.5mm mounting holes.
