Adafruit BNO085 9-DOF Orientation IMU Fusion Breakout
Overview
The Adafruit 4754 is a high-performance 9-DOF orientation sensor breakout based on the BNO085 System-in-Package (SiP). It combines a 3-axis accelerometer, gyroscope, and magnetometer with an ARM Cortex-M0 processor that runs Hillcrest Labs' SH-2 proprietary sensor fusion software to provide accurate quaternions, Euler angles, and rotation vectors.
Why Choose This Part
The BNO085 offloads complex sensor fusion calculations to an internal ARM Cortex-M0, reducing host MCU overhead and eliminating the need for custom Kalman filter implementations. The breakout includes onboard level shifting and a 3-5V compatible voltage regulator, making it directly compatible with both 3.3V and 5V logic systems.
Applications
Key Specifications
Getting Started
Connect the board to an Arduino or Raspberry Pi via the I2C interface using the STEMMA QT connectors for a solderless setup. Adafruit provides comprehensive libraries for Arduino and CircuitPython to interface with the SH-2 protocol over I2C, SPI, or UART.
