Fermion: BMM150 Triple Axis Magnetometer Sensor (Breakout)

The BMM150 is an outstanding low-power, low-noise 3-axis digital geomagnetic sensor that meets the demands of compass applications perfectly. Leveraging Bosch's exclusive FlipCore technology, it offers high-accuracy absolute spatial orientation and motion vectors with great dynamics. With its compact size and light weight, it's ideal for providing accurate heading support for drones. It can also be paired with an inertial measurement unit composed of a 3-axis accelerometer and a 3-axis gyroscope. Board Overview: Connect the module to the Raspberry Pi as shown. The default address is 0x13. Connect the sensor to the M0 (or other mainboards) as per the diagram.

Using the Fermion BMM150 Three - Axis Digital Magnetometer Sensor Breakout Module is easy. First, connect the module to your Raspberry Pi following the provided connection guide. Remember, the default address is 0x13. If you're using an M0 or other mainboards, refer to the diagram for the right way to connect the sensor. When it comes to using this sensor, make sure the power supply is set to 3.3V. The sensor can work in a temperature range from -40 to 85°C, so avoid using it in extremely cold or hot environments outside this range. For maintenance, keep the sensor clean and free from dust. Since it has a low - power preset mode with an average current consumption of 170μA, you can use this mode to save power when high - speed performance isn't necessary. The normal mode, with a 500μA average current consumption, is better for tasks that need more speed and accuracy. If you need to understand the readings, the magnetometer has a heading accuracy of 30μT for the horizontal geomagnetic field component, with an error of only ±2.5°. The start - up time is just 3ms, so it's ready to go quickly. Also, note that the sensor has a programmable interrupt feature, which can be set according to your specific needs.
