## Description

The BNO085 from Hillcrest Laboratories is a 9-DOF IMU with built-in sensor fusion — it combines accelerometer, gyroscope and magnetometer data on-chip and delivers ready-to-use orientation, motion detection and activity classification outputs. No external sensor fusion algorithms needed. The BNO085 uses the same hardware as the BNO055 but runs Hillcrest's SH-2 firmware, which provides significantly more output types including AR/VR-optimised rotation vectors, tap/step/shake detection, and activity classification. It also fixes the SPI timeout bug present in the BNO080, and is fully backward-compatible with BNO080 code. Sensor Fusion Outputs Rotation Vector – Four-point quaternion for accurate orientation AR/VR Rotation Vectors – Optimised for augmented/virtual reality with low latency Linear Acceleration – Acceleration minus gravity in m/s² Gravity Vector – Gravitational acceleration in m/s² Calibrated Accelerometer, Gyro & Magnetometer – Individual sensor readings available simultaneously Uncalibrated + Raw Outputs – ADC-level data for custom processing Detection & Classification Activity Classification – Identifies movement type (walking, running, still, etc.) Stability Detection – Reports stable vs unstable states Tap Detector – Single and double tap detection Step Detector & Counter – Pedometer functionality Shake Detector – Identifies shake gestures Significant Motion Detector – Triggers on meaningful movement Key Features On-Chip Sensor Fusion – ARM Cortex M0 processor running Hillcrest SH-2 firmware Multiple Interfaces – I2C, SPI and UART supported UART-RVC Mode – Simple heading and acceleration output over UART, ideal for robot vacuum cleaners and basic orientation tasks STEMMA QT / Qwiic Connectors – Solderless I2C connection Wide Voltage Range – 3–5V power and logic with on-board regulator and level shifting External Crystal – 32.768 kHz crystal for stable reference BNO085 vs BNO055 Same hardware (accelerometer, gyro, magnetometer) BNO085 runs Hillcrest SH-2 firmware with significantly more output types BNO085 adds AR/VR rotation vectors, activity classification, tap/step/shake detection BNO085 provides calibrated, uncalibrated and raw sensor outputs simultaneously BNO085 includes UART-RVC mode for simple heading output Also Available BNO055 STEMMA QT – Simpler sensor fusion with Euler angle output BNO055 Breakout – Original BNO055 breakout board Ideal For Robotics and drone navigation AR/VR head tracking and motion controllers Activity and gesture recognition Robot vacuum cleaners (UART-RVC mode) Motion tracking and orientation sensing Package Contents 1× Adafruit BNO085 IMU Fusion Breakout with STEMMA QT (assembled and tested) 1× Header strip
