Adafruit 4479 Adafruit Three-Axis Magnetometer - LIS3MDL - Stemma QT/Qwiic
Capture the magnetic fields that surround us with this handy 3-axis magnetometer module (compass). Magnetometers can detect where the strongest magnetic force is coming from, generally used to detect magnetic north, but can also be used to measure magnetic fields. This sensor tends to combine with a 6-DoF (degree of freedom) accelerometer to create a 9-DoF inertial measurement unit that can detect its orientation in real space thanks to the Earth's stable magnetic field. It's a great addition to ST's LSM6DSOX! We based this breakout on ST's LIS3MDL, a great general purpose magnetometer. This compact sensor uses I2C to communicate and is very easy to use. Just download our library and connect SCL pin to your I2C clock pin and SDA pin to your I2C data pin and upload our test program to read out magnetic field data. If you want, you can also use SPI to receive data (we prefer just I2C here. This sensor can be between +-4 Gauss (+- 400 uTesla) to +-16 Gauss (+- 1600 uT or 1.6 mT ).For ultra high precision, an update rate of 155Hz is recommended - but if you don't mind, the sensor can output at 1000Hz. To make life easier so you can focus on your important work, we have took the LIS3MDL and mounted it on a breakout PCB along with support circuitry so you can use this little wonder at 3.3V (Feather/Raspberry Pi) or 5V (Arduino/Metro328) logic level. Since it I2C speaks, you can simply connect it with two wires (plus power and ground). We've even included SparkFun Qwiic compatible STEMMA QT connectors for the I2C bus, so you don't even need to solder. Just plug it into your favorite microphone and you're ready to use ours Use CircuitPython/Python or Arduino drivers to easily connect to the LIS3MDL and get magnetic measurements as quickly as possible.
