Product Description
Product Description
The Fermion: BMM150 Triple Axis Magnetometer Sensor (Breakout) is a compact 3-axis magnetometer sensor module for geomagnetic field detection and heading measurement in embedded systems. The module is based on the Bosch BMM150 and is designed for low-power operation. It is suitable for digital compass functions, orientation sensing, and for complementing inertial systems that use accelerometers and gyroscopes.
Communication is available via either I2C or SPI. According to the source data, the default I2C address is 0x13. With low current consumption, short startup time, and a compact breakout format, the module can be integrated into mobile, battery-powered, and space-constrained designs. The specified low noise and magnetic resolution support stable signal acquisition for heading and motion-related applications.
