Description
The Adafruit 9-DOF Absolute Orientation IMU Fusion Breakout in Stemma QT format integrates BNO055 that is a a MEMS accelerometer, magnetometer, and gyroscope, and putting them on a single die with a high-speed ARM Cortex-M0 based processor to digest all the sensor data, abstract the sensor fusion and real-time requirements away, and spit out data you can use in quaternions, Euler angles or vectors.
- Uses I2C address 0x28 (default) or 0x29
The BNO055 can output the following sensor data:
- Absolute Orientation (Euler Vector, 100Hz) Three axis orientation data based on a 360° sphere
- Absolute Orientation (Quaternion, 100Hz) Four point quaternion output for more accurate data manipulation
- Angular Velocity Vector (100Hz) Three axis of 'rotation speed' in rad/s
- Acceleration Vector (100Hz) Three axis of acceleration (gravity + linear motion) in m/s^2
- Magnetic Field Strength Vector (20Hz) Three axis of magnetic field sensing in micro Tesla (uT)
- Linear Acceleration Vector (100Hz) Three axis of linear acceleration data (acceleration minus gravity) in m/s^2
- Gravity Vector (100Hz) Three axis of gravitational acceleration (minus any movement) in m/s^2
- Temperature (1Hz) Ambient temperature in degrees celsius
STEMMA QT / Qwiic 4-pin 1mm Pitch White Female Connector Cable 150mm Long - Both Side can be purchased seperately.
