Adafruit BNO055 9-DOF Absolute Orientation Sensor
Overview
The Adafruit 2472 is an evaluation board for the Bosch BNO055, a System-in-Package that integrates a triaxial accelerometer, gyroscope, and geomagnetic sensor. Unlike standard IMUs that provide raw data, this board features an internal processor that runs Bosch's Sensor Fusion algorithms to output absolute orientation in quaternions, Euler angles, or vectors.
Why Choose This Part
The primary advantage is the onboard sensor fusion which offloads complex Kalman filter math from the host MCU, saving memory and cycles. It handles tilt compensation and magnetic distortion internally, providing a stable -40 to +85 degrees Celsius operating range for diverse environments.
Applications
Getting Started
Connect the board via the I2C interface to any microcontroller like an Arduino or Raspberry Pi. Adafruit provides comprehensive libraries for C++ and CircuitPython to read orientation data immediately. The board includes a 3.3V regulator and level shifting, making it compatible with both 3V and 5V logic levels.
