Bosch BMM150 3-Axis Digital Geomagnetic Sensors

Bosch BMM150 3-Axis Digital Geomagnetic Sensors are low-power, low-noise 3-axis digital geomagnetic sensors that match the requirements of compass applications. By means of sensor data fusion software tailored to the hardware, Bosch BMM150 Geomagnetic Sensors provide absolute spatial orientation and motion vectors with high accuracy and dynamics. BMM150 is also especially suited for supporting drones in accurate heading. The 12-pin wafer level chip scale package (WLCSP) with a footprint of 1.56mm x 1.56mm and a height of 0.60mm provides high design flexibility for the development of mobile devices.
