This board is a compact (0.4″ × 0.9″) breakout board for ST’s LIS3MDL three-axis digital magnetic sensor; we therefore recommend careful reading of the LIS3MDL datasheet (2MB pdf) before using this product. The LIS3MDL is a great IC, but its small package makes it difficult for the typical student or hobbyist to use. It also operates at voltages below 3.6 V, which can make interfacing difficult for microcontrollers operating at 5 V.


This carrier board addresses these issues by incorporating additional electronics, including a 3.3 V voltage regulator and level-shifting circuits, while keeping the overall size as compact as possible. The board ships fully populated with its SMD components, including the LIS3MDL, as shown in the product picture.


The LIS3MDL has many configurable options, including four selectable sensitivity (gain) settings, a wide choice of output data rates, and a programmable external interrupt signal. The three magnetic field strength readings are available through a digital interface, which can be configured to operate in either I²C (TWI) or SPI mode.


The carrier board includes a low-dropout linear voltage regulator that provides the 3.3 V required by the LIS3MDL, which allows the sensor to be powered from a 2.5-5.5 V supply. The regulator output is available on the VDD pin and can supply almost 150 mA to external devices. The breakout board also includes a circuit that shifts the I²C clock and data lines to the same logic voltage level as the supplied VIN, making it simple to interface the board with 5 V systems, and the board’s 0.1″ pin spacing makes it easy to use with standard solderless breadboards and 0.1″ perfboards.

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.
