Adafruit 9-DOF Absolute Orientation IMU Fusion Breakout - BNO055 - STEMMA QT / Qwiic

The Adafruit BNO055 STEMMA QT breakout delivers complete 9-DOF orientation sensing with onboard sensor fusion and plug-and-play I2C connectivity. 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.

This STEMMA QT version is smaller than the original breakout and features Qwiic-compatible connectors on both sides for no-solder I2C wiring. The same libraries and code work on both versions.

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)
• Gravity Vector – Three-axis gravitational acceleration in m/s² (100 Hz)
• Magnetic Field Strength – Three-axis in µT (20 Hz)
• Temperature – Ambient temperature in °C (1 Hz)
