2.1.4 Bosch BMI160 Inertial Measurement Sensor
®
The Bosch BMI160 inertial measurement unit is a 6-axis digital accelerometer and gyroscope sensor that
measures gravitational forces exerted on the EVM as well as speed of rotation in degrees per second. The
BMI160 can synchronize its own accelerometer and gyroscope data as well as with an external device
such as a geomagnetic sensor. Rotating the board about its axis increases the gyroscope output of the
sensor, and changing the orientation of the board with respect to the earth changes its accelerometer
output (for example, with the X arrow toward the earth, the X value of the accelerometer is positive). The
BMI160 has a secondary I
geomagnetic sensor. The digital output of both sensors is reported over an I
wire serial interface. The reference designator for the BMI160 is U3.

2.1.5 Bosch BMM150 Geomagnetic Sensor
The Bosch BMM150 geomagnetic sensor is a 3-axis digital magnetometer sensor that measures the
strength of magnetic fields in microtesla for e-compass applications. The BMM150 can be used in
combination with the BMI160 for 9-axis sensing. Placing a magnet near the sensor increases the sensor
output. The BMM150 is connected to the BMI160 as a secondary I
passed to the BMI160 to be reported out over an I
reference designator for the BMM150 is U2.
