Summary

LIS3MDL 3-axis magnetic compass with I²C interface for detecting magnetic fields and orientation.

Description

The **LIS3MDL Magnetic Compass** measures the X, Y, and Z components of magnetic fields. It supports configurable sample rates, full-scale range, power modes, and self-test functionality. Temperature compensation can be enabled, and performance modes for XY and Z axes can be individually set. The sensor communicates via I²C and can be reset or synchronized using a clock input.
