Summary

Bosch BNO055 9-axis absolute orientation sensor with I²C interface combining accelerometer, gyroscope, magnetometer, and sensor fusion.

Description

The **BNO055 IMU** combines a 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer with integrated sensor fusion for absolute orientation measurement. It provides raw sensor data, fused orientation data, quaternion output, and Euler angles with configurable operation modes, calibration, and power settings.
