This module is a carrier/breakout board for the ST LIS3MDL three-axis magnetometer. The sensor provides magnetic field strength measurements with a configurable range of ±4 gauss to ±16 gauss that can be read through a digital I²C or SPI interface. The board includes a 3.3 V voltage regulator and integrated level shifters that allow operation from 2.5 to 5.5 V, and the 0.1″ pin spacing makes it easy to use with standard solderless breadboards and 0.1″ perfboards.
