Product Overview: GY-BNO055 9DOF Absolute Orientation Sensor
The GY-BNO055 is a sophisticated 9-axis Inertial Measurement Unit (IMU) designed to provide “Absolute Orientation.” By offloading complex calculations to its internal processor, it delivers stable, drift-compensated data that is ready to use immediately for robotics and VR applications.
Core Specifications & Features
- Integrated 9-Axis Sensing: Combines a 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer into a single package.
- Onboard ARM Cortex-M0 Processor: Features a dedicated high-speed processor to handle complex math internally.
- Real-Time Sensor Fusion: Delivers stable orientation data (Quaternions, Euler Angles, or Rotation Vectors) without taxing your microcontroller’s CPU.
- High-Precision Output: Provides absolute orientation (relative to the Earth’s magnetic field) with high stability and minimal drift.
- Simplified Integration: Removes the need for writing complex Kalman or Madgwick filter algorithms in your own code.
- Flexible Communication: Supports both I2C and UART (Serial) interfaces for easy connection to Arduino, ESP32, or Raspberry Pi.
- Absolute Heading: The magnetometer integration allows for a true “North” reference, unlike standard 6-axis IMUs.
