Key Features
- Triple-axis magnetometer (compass) module
- Sense ranges from +-50 gauss (+- 5000 uTesla!)
- Pair with a 6-DoF (degree of freedom) 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
- SparkFun qwiic compatible STEMMA QT connectors for the I2C bus so you don't even need to solder
Sense the magnetic fields that surround us with this handy triple-axis magnetometer (compass) 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 (degree of freedom) 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. It's a great match for the LSM6DSOX from ST!
Adafruit based this breakout on ST's LIS2MDL, a great general purpose magnetometer with a very wide range and bot I2C and SPI interfaces. This compact sensor uses I2C to communicate and it's very easy to use. Simply download Adafruit's library and connect the 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'd like, you can also use SPI to receive data (we just happen to prefer I2C here)
This sensor can sense ranges from +-50 gauss (+- 5000 uTesla!) with no range-setting required. For high resolution, you can read at 100 Hz update rate. If you don't mind a little loss of precision, the sensor can output at 150 Hz.
