Product Overview
The BNO055 9-Axis Absolute Orientation Sensor is an all-in-one “System in Package” (SiP) solution designed to eliminate the complexity of motion-sensing algorithms. Unlike standard IMUs that provide raw data requiring heavy external processing, the BNO055 features an integrated 32-bit ARM Cortex-M0+ microcontroller. This onboard processor runs proprietary sensor fusion software (BSX3.0 FusionLib) to deliver ready-to-use, drift-free orientation data directly to your application.
Whether you are developing autonomous drones, industrial robotics, or high-precision AR/VR wearables, this module provides a “plug-and-play” experience by handling all the complex math internally.
Key Features
  • Integrated Sensor Fusion: Onboard MCU processes raw data from the accelerometer, gyroscope, and magnetometer to output stable Euler angles and Quaternions.
  • Nine Degrees of Freedom (9-DoF): Comprehensive motion tracking across three axes for acceleration, rotation, and magnetic field strength.
  • Intelligent Self-Calibration: Continuously calibrates itself during operation to adjust for environmental changes like temperature shifts or magnetic interference.
  • Multiple Data Outputs: Simultaneously provides absolute orientation, angular velocity, linear acceleration, gravity vectors, and ambient temperature.
  • Professional Reliability: Rated for industrial temperatures (-40°C to +85°C), ensuring performance in demanding outdoor or factory environments.
  • Flexible Communication: Supports both I²C and high-speed UART interfaces for seamless connection to Arduino, Raspberry Pi, ESP32, and STM32.
Usage & Applications
  1. Robotics: Use absolute orientation (quaternions) for precise limb movement and chassis stabilization in autonomous mobile robots.
  2. Drones & UAVs: The 100Hz update rate and gravity vector output are critical for flight stabilization and level-keeping.
  3. Industrial Leveling: High-accuracy tilt sensing and motion detection for heavy machinery or automated guidance systems.
  4. Navigation: Combines magnetic heading with motion data for indoor navigation and dead reckoning where GPS is unavailable.
Q: Does the BNO055 require an external library for sensor fusion?

No. The sensor fusion is handled entirely by the onboard 32-bit MCU. While you need a simple driver to read the data via I²C/UART, your host controller (like an Arduino) does not need to perform any complex fusion math.

Q: How do I calibrate the sensor?

The BNO055 features automatic background calibration. For the magnetometer, simply move the sensor in a “figure-8” pattern; for the gyroscope, leave it still for a few seconds; and for the accelerometer, place the module in 6 different orientations.

Q: What is the advantage of Quaternions over Euler angles?

Euler angles (Roll, Pitch, Yaw) are easy for humans to read but suffer from “Gimbal Lock” at certain angles. Quaternions are recommended for professional robotics and 3D modeling as they provide continuous, error-free orientation in all 360 degrees of motion.

Q: Can this be used in environments with magnetic interference?

The BNO055 includes an “NDOF” mode that uses all sensors to compensate for magnetic distortions. However, for best results, it should be mounted away from motors, magnets, or large metal structures.

Q: Is this module suitable for industrial volume purchasing?

Yes. The BNO055 is a mature, professional-grade solution with high reliability and a wide operating temperature range, making it a standard choice for OEM integration in commercial products.
