IMU orientation on EmotiBit

The EmotiBit uses the BMI160 for Accelerometer and Gyroscope measurements. BMM150 is used for Magnetometer readings.

The figure below shows the orientation of the IMU ICs on EmotiBit v4+ (not to scale). The circle inside IC boundary indicates the orientation marker.

For more details on the resulting X, Y and Z coordinate axis, check out:

• section 2.6.5 (Orientation recognition) in the BMI160 datasheet
• section 8.2 (Sensing axes orientation) in the BMM150 datasheet.
