Smart sensor: BHA250B
Ready to use firmware files
Without any additionally attached sensors the BHA250B provides a three axis solution out of the box, implementing the following sensor types: Accelerometer, Step counter, Step detector, Significant motion, Tilt detector, Pickup gesture, Wake up gesture, Glance gesture, Activity recognition of standing, walking, running, biking, in vehicle
By attaching an external magnetometer to the smart-hub interface and using one of the RAM firmware files listed below to include the sensor driver for the corresponding magnetometer the BHA250B is instantaneously offering a robust eCompass solution by providing the following sensor types on top: Gravity, Linear acceleration, Geomagnetic field, Magnetic field uncalibrated, Orientation, Rotation vector, Geomagnetic rotation vector.
Bosch Sensortec BMM150 Extension
The BMM150 is a low power and low noise 3-axis digital geomagnetic sensor to be used in compass applications. The 12-pin wafer level chip scale package (WLCSP) with a footprint of 1.56 x 1.56 mm² and 0.60 mm height provides highest design flexibility to the developer of mobile devices.

The small package of AK09911 incorporates magnetic sensors for detecting terrestrial magnetism in the X-axis, Y-axis, and Z-axis, a sensor driving circuit, signal amplifier chain, and an arithmetic circuit for processing the signal from each sensor.
Asahi Kasei AK09912 Extension
AK09912 is a 3-axis electronic compass IC with high sensitive Hall sensor technology offering an output data resolution of 16-bit (0.15 μT/LSB). The small package of AK09912 incorporates magnetic sensors for detecting terrestrial magnetism in the X-axis, Y-axis, and Z-axis, a sensor driving circuit, signal amplifier chain, and an arithmetic circuit for processing the signal from each sensor.
Yamaha YAS532 Extension
The YAS532B is a 3-axis geomagnetic sensor device with the following circuits integrated on one chip: a buffer amplifier, an AD converter, a clock generator circuit, and a serial data interface circuit (compliant with I2C bus interface).
Hint: If you are designing your own PCB make sure to align the pin1 marking of your BHA250B and the Magnetometer of your choice in the PCB layout for plug-and-play axis alignment of your system. Following this recommendation ensures a proper absolute orientation out of the box without the need of a subsequent axis remapping of the x, y and z-axis of BHA250B and the Magnetometer. Regarding landing pattern design and connection diagrams please refer to the corresponding product data sheets of the devices.
