## Description

Sense the magnetic fields that surround Adafruit 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.

Adafruit based this breakout on the [QMC5883P](https://www.qstcorp.com/en_comp_prod/QMC5883P), a magnetometer Adafruit see used in may Quadcopter and robotic builds. 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 Adafruit's test program to read out magnetic field data.

This sensor can sense ranges from +-2 Gauss (+- 200 uTesla) up to +-30 gauss (+- 3000 uT or 3.0 mT). With 16-bit ADC and settings for over-sampling and down-sampling, you can set it up to get just the right range and precision.

To make life easier so you can focus on your important work, Adafruit have taken the QMC5883P and put it onto a breakout PCB along with support circuitry to let you use this little wonder with 3.3V (Feather/Raspberry Pi) or 5V (Arduino/ Metro328) logic levels. Additionally, since it speaks I2C you can easily connect it up with two wires (plus power and ground!). Adafruit have even included [SparkFun qwiic](https://core-electronics.com.au/catalogsearch/result/?q=qwiic) compatible **[STEMMA QT](https://learn.adafruit.com/introducing-adafruit-stemma-qt)** connectors for the I2C bus so **you don't even need to solder!** Just wire up to your favorite micro and you can use Adafruit's CircuitPython/Python or [Arduino drivers to easily interface with the QMC5883P](https://github.com/adafruit/Adafruit_QMC5883P) and get magnetic measurements ASAP. [**QT Cable is not included**, but Adafruit have a variety in the shop](https://core-electronics.com.au/search?q=stemma+qt+cable).

It's fully assembled and tested. Comes with a bit of 0.1" standard header in case you want to use it with a breadboard or perfboard. Four 2.5mm (0.1") mounting holes for easy attachment.
