7Semi BNO085 9-DOF Orientation IMU Fusion Breakout Qwiic

The 7Semi BNO085 9-DOF Orientation IMU Fusion Breakout (Qwiic) is a high-performance inertial measurement unit based on the BNO085 sensor from CEVA-Hillcrest. It combines a 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer with an onboard sensor-fusion engine, delivering accurate absolute orientation data without heavy processing load on the host microcontroller. With Qwiic connectors and multiple communication interfaces, it is ideal for motion tracking, navigation, and robotics applications.
