The VR IMU uses the impressive BNO080 IMU. The IC features a three-axis accelerometer/gyroscope/magnetometer combination that runs alongside the ARM Cortex M0 + to run powerful algorithms. The BNO080 Inertial Measurement Unit (IMU) generates accurate rotation vector headings, ideal for VR and other heading applications, with a static rotation error of 2 degrees or less. The IC is designed to be implemented in Android-based phones to handle all the calculations required for virtual reality goggles using only your phone. The sensor is very powerful and the power is very complex. An I2C-based library is provided, which provides rotation vectors (which most people want to read from IMUs) as well as acceleration, gyroscope and magnetometer readings, step counts, activity sorters (such as cycling), and calibration. The VR IMU has created a demo processing application to see how the motion of the IMU can accurately manipulate 3D objects using the quaternion output of the IMU. This version features onboard 32kHz crystals for improved accuracy and more accurate timestamping. Interfaces:The BNO080 can communicate through a variety of interfaces. The Qwiic VR IMU has two jumpers that allows the user to select their interface of choice. I2C (Default): Up to 400kHz SPI: Up to 3MHz UART: 3Mbps UART-RVC (Robot Vacuum Cleaners): 115200kbps Performance: 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: 0.35m/s2 Accelerometer Accuracy: 0.3m/s2 Gyroscope Accuracy: 3.1/ sec Magnetometer Accuracy: 1.4T Due to different product batches, the appearance may vary, which does not affect the use.
