Gravity - 3-axis magnetometer - BMM150 - I2C - DFRobot SEN0529
DFRobot three-axis magnetometer with Bosh BMM150 system based on FlipCore technology. The module allows you to measure the magnetic field in three perpendiculars in the range of ± 1300 uT (X and Y axis) and ± 2500 uT (Z axis) with a measurement resolution of 0.3 uT . The module provides information on absolute orientation while maintaining high accuracy and precision of measurements.

Product description: Gravity - 3-axis magnetometer - BMM150 - I2C - DFRobot SEN0529
DFRobot three-axis magnetometer with Bosh BMM150 system based on FlipCore technology. The module allows you to measure the magnetic field in three perpendiculars in the range of ± 1300 uT (X and Y axis) and ± 2500 uT (Z axis) with a measurement resolution of 0.3 uT . The module provides information on absolute orientation while maintaining high accuracy and precision of measurements. The board has a Gravity connector that allows for quick connection of elements. The sensor uses the I2C bus to communicate with connected devices. It also has a 2-bit DIP switch that can be used to configure the I2C address (4 addresses available). The module with the BMM150 system is used in such areas as navigation and positioning of robots, electric compass, electric map.
Energy-saving three-axis geomagnetic sensor from DFRobot.
The product is compatible with Arduino

Pinout description and connection diagram
The module has outputs in the form of soldering pads, to which the goldpin strip included in the set should be soldered, and the Gravity connector for connection without soldering. Each pin has been described, which makes it much easier to connect.
- VCC - power pin in the range from 3.3 V to 5 V DC
- GND - system ground
- SCL - clock line of the I2C interface
- SDA - data line of the I2C interface
- INT - interrupt pin
