Adafruit 9-DOF Absolute Orientation IMU Fusion Breakout - BNO055

The Adafruit BNO055 breakout delivers complete 9-DOF orientation sensing with onboard sensor fusion — no complex algorithms to write yourself. The Bosch BNO055 combines an accelerometer, gyroscope, and magnetometer on a single die with an ARM Cortex-M0 processor that handles all fusion calculations internally, outputting ready-to-use orientation data over I2C.

The breakout includes a 3.3V regulator, logic level shifting for I2C and reset pins, and an external 32.768 KHz crystal for optimal performance. Interrupt and address-selection pins are broken out for advanced configurations.

Sensor Outputs

• Absolute Orientation (Euler) – Three-axis orientation on a 360° sphere (100 Hz)
• Absolute Orientation (Quaternion) – Four-point quaternion for precise manipulation (100 Hz)
• Angular Velocity – Three-axis rotation speed in rad/s (100 Hz)
• Acceleration – Three-axis gravity + linear motion in m/s² (100 Hz)
• Linear Acceleration – Three-axis acceleration minus gravity in m/s² (100 Hz)
