Adafruit 9-DOF Orientation IMU Fusion Breakout - BNO085 (BNO080) - STEMMA QT / Qwiic

The 9-DOF Orientation IMU Fusion Breakout with BNO085 is a compact motion sensor for projects that need directly usable orientation and movement data. This breakout combines a 3-axis accelerometer, gyroscope and magnetometer with built-in sensor fusion, helping you work with stable and consistent measurements more quickly.

With its integrated Arm Cortex-M0 and SH-2 firmware, the module provides acceleration, angular velocity, magnetic field strength, linear acceleration, gravity vector and quaternion data. It also supports advanced detection and classification features such as tap, step, shake and significant motion detection, along with activity classification. The breakout includes level shifting for 3.3V and 5V logic, two STEMMA QT connectors and a breadboard-friendly format.
