Adafruit Triple-axis Magnetometer - LIS3MDL

Sense the magnetic fields that surround us with this handy triple-axis magnetometer module. Magnetometers can sense where the strongest magnetic force is coming from, generally used to detect magnetic north, but can also be used for measuring magnetic fields.

This sensor tends to be paired with a 6-DoF accelerometer/gyroscope to create a 9-DoF inertial measurement unit that can detect its orientation in real space thanks to Earth's stable magnetic field. This compact sensor uses I2C to communicate, making it very easy to use. Simply connect the SCL pin to your I2C clock pin and SDA pin to your I2C data pin, then upload our test program to read out magnetic field data.

This sensor can sense ranges from ±4 gauss (±400 uTesla) up to ±16 gauss (±1600 uT or 1.6 mT). For ultra-high precision, a 155 Hz update rate is recommended, but if you don't mind a little loss of precision, the sensor can output at 1000 Hz.

We've taken the LIS3MDL and placed it onto a breakout PCB along with support circuitry, allowing you to use this module with 3.3V or 5V logic levels. With SparkFun Qwiic compatible STEMMA QT connectors for the I2C bus, you can connect it with two wires without needing to solder.

Fully assembled and tested, it comes with 0.1" standard header for breadboard or perfboard integration, and includes four 2.5mm mounting holes for easy attachment.
