Product Descriptions

BNO080/085 is a 9-axis system in package (SiP) that enables rapid development of sensor supported augmented reality (AR), virtual reality (VR), robots, and IoT devices. It was jointly developed by Bosch and Hillcrest Labs, featuring high-performance accelerometers, magnetometers, and gyroscopes, and adopts a low-power 32-bit ARM Cortex M0+MCU in a small package. Hillcrest's Freespace ® The sensor hub software is pre integrated on BNO080/085, providing excellent 9-axis and 6-axis motion tracking, enabling exciting sensor applications in various consumer and IoT products.

BNO080/085 provides application specific configuration, functionality, and performance in a small turnkey component, benefiting OEMs by shortening product time to market, reducing development time and BOM costs, and providing the highest precision and quality.

The VR IMU uses the impressive BNO080 IMU. This IC features a combination of three-axis accelerometer/gyroscope/magnetometer, running together with ARM Cortex M0+to run powerful algorithms. The BNO080 Inertial Measurement Unit (IMU) can generate accurate rotation vector titles, making it ideal for VR and other heading applications with static rotation errors of 2 degrees or less. This is what we have been waiting for: all sensor data is combined and drift corrected into meaningful, accurate IMU information.

This IC is designed to be implemented in Android based smartphones to handle all the calculations required for virtual reality goggles using only your phone. The sensor function is very powerful, and the power is also very complex. Provides an I2C based library that provides rotation vectors (most people want to read from IMU) as well as acceleration, gyroscope and magnetometer readings, steps, activity classifiers (such as cycling), and calibration.

VR IMU has created a demonstration processing application to see how IMU motion accurately manipulates 3D objects using IMU's quaternion output.

If I2C is not your first communication option, the sensor can also communicate through SPI and UART! If you are using UART, we recommend using Serial Basic for easy connection.

This version uses onboard 32kHz crystals, which can improve accuracy and provide more accurate timestamps.
