• Product Description

    BMC050 (not for new design-ins)

    The BMC050 is a fully compensated electronic compass including a triaxial geomagnetic sensor and a triaxial acceleration sensor (6 degrees of freedom) that delivers excellent performance in very small size. The BMC050 allows for determining precise tilt-compensated geomagnetic heading information and for providing accurate acceleration sensor data.

    The BMC050 6-axis, digital e-compass comes in a small 3 x 3 x 0.95 mm³ LGA package. It comprises Bosch Sensortec proprietary FlipCore geomagnetic sensing technology with Bosch Sensortec’s well-proven, leading edge MEMS sensor technology for the accelerometer.


    Accurate tilt-compensated orientation information for:

    - navigation (GPS enhancement / map rotation)

    - location based services (LBS)

    - augmented reality

    - in combination with a pressure sensor for indoor navigation


    Mobile Applications

    Would you like to check an altitude on a map and plan the the best route or check the local weather forecast for your next hike? Are you monitoring your daily sports acitivities with your smartphone? These and many more outdoor applications are enabled by MEMS sensors. These new and advanced devices will even help you to find your car in a public parking garage.
