The VR IMU uses the BNO080 IMU, which features a three-axis accelerometer, gyroscope, and magnetometer combined with an ARM Cortex M0+ processor to run advanced sensor fusion algorithms. The BNO080 Inertial Measurement Unit generates accurate rotation vector data, ideal for VR and orientation sensing applications, with a static rotation error of 2 degrees or less. Designed for integration with mobile devices, the IC handles sensor processing required for virtual reality applications. The sensor delivers high performance with complex internal processing. An I2C-based library is provided, offering access to rotation vectors, acceleration, angular velocity, magnetic field readings, step counting, activity classification (e.g., cycling), and sensor calibration. A demo application is available to demonstrate how the IMU's quaternion output can be used to accurately control and manipulate 3D objects in real time. This version includes onboard 32kHz crystals for enhanced timing accuracy and improved data synchronization. Interfaces: The BNO080 supports multiple communication interfaces. The VR IMU includes jumpers to select the desired mode: - I2C (Default): Up to 400kHz - SPI: Up to 3MHz - UART: 3Mbps - UART-RVC (Robot Vacuum Cleaner mode): 115200bps Performance Specifications: Rotation Vector: - Dynamic Error: 3.5° - Static Error: 2.0° Gaming Rotation Vector: - Dynamic Error: 2.5° - Static Error: 1.5° Heading Drift: 0.5°/min Geomagnetic Rotation Vector: - Dynamic Rotation Error: 4.5° - Static Rotation Error: 3.0° Gravity Angle Error: 1.5° Linear Acceleration Accuracy: 0.35 m/s² Accelerometer Accuracy: 0.3 m/s² Gyroscope Accuracy: 3.1°/sec Magnetometer Accuracy: 1.4 μT Color: As Shown Material: Polycarbonate (PC) Package Contents: 1 x Sensor Module Only the items listed above are included.
