Supply voltage 3.3v, provide arduino library files.The BNO080 / 085 is a 9-axis system-in-package (SiP) for rapid development of sensor-enabled augmented reality (AR), virtual reality (VR), robotics and IoT devices. Co-developed by Bosch and Hillcrest Labs, it features high-performance accelerometers, magnetometers and gyroscopes in a low-power 32-bit ARM Cortex M0 + MCU in a small package. Hillcrest’s Freespace sensor hub software is pre-integrated on the BNO080 / 085 to provide superior 9-axis and 6-axis motion tracking. Enables exciting sensor applications in a variety of consumer and IoT products

The BNO080 / 085 offers application-specific configuration, functionality and performance in a small turnkey assembly that benefits OEMs by reducing time-to-market, development time and BOM costs, as well as providing the highest level of accuracy and quality.

The VR IMU uses the impressive BNO080 IMU. this IC features a 3-axis accelerometer/gyroscope/magnetometer combination running with the ARM Cortex M0 + running powerful algorithms. The BNO080 Inertial Measurement Unit (IMU) generates accurate rotation vector headings, ideal for VR and other heading applications, with static rotation errors of 2 degrees or less. This is what we’ve been waiting for: all sensor data combined and drift-corrected into meaningful, accurate IMU information.

The IC is designed to be implemented in an Android-based phone to handle all the calculations needed for virtual reality goggles using only your phone. The sensor functionality is very powerful and the power is complex. An I2C based library is provided which provides rotation vectors (which most people want to read from the IMU) as well as acceleration, gyroscope and magnetometer readings, step count, activity classifier (e.g. cycling) and calibration.

VR IMU has created a demo processing application to see how IMU’s motion can accurately manipulate 3D objects using IMU’s quaternion output.

If I2C is not your first communication choice, the sensor is also capable of communicating via SPI and UART! If you are using a UART, we recommend that you use Serial Basic for easy connection.

This version uses an on-board 32 kHz crystal for increased precision and more accurate timestamps.

Hillcrest Labs, a subsidiary of InterDigital and a world-renowned provider of motion control software hardware, today announced its newest sensor chip, the BNO085 with a 9-axis System-in-Package (SiP), paired with an enhanced sensor fusion algorithm specifically designed for virtual reality (VR), augmented reality (AR) and 3D audio applications. VR systems using the BNO085 benefit from the sense of picture stabilization that comes from more precise calibration between the control handle and the headset, even when the control handle is not in the field of view of the system camera.

The BNO085 inherits all the same features of its predecessor, the BNO080. The latter is now widely used in VR, AR, 3D audio, robotics, and IoT devices. It combines Hillcrest Labs’ high-performance, proprietary MotionEngine sensor processing software combined with accelerometers, magnetometers, gyroscopes and a low-power 32-bit ARM Cortex M0+ MCU in a single package.The BNO085 offers unique sensor fusion, motion tracking and exclusive application features to support a range of applications The BNO085 is newly designed to provide precise dynamic tracking for VR controllers in internal and external systems for VR, AR and 3D audio headsets.

Improvements to the BNO085 designed for VR systems include:

-Improved dynamic tracking through internal and external camera system improvements;

-Significantly reduced latency errors to keep the control handle in line with the headset’s picture frequency;

-Tight synchronization of the operating effect between the dual control handles in the dual control handle system

-Even outside the camera’s field of view, the sensor can track the rotational movement of one or more control handles, smoothly oriented output screen.

Compared to its predecessor, the BNO085 features low power consumption and compact size while providing low latency, 1KHz sampling rate, smooth directional output, and accurate dynamic tracking capabilities. Developers and system integrators benefit from faster time to market, reduced development time, reduced BOM costs, and the highest level of accuracy and product quality. Two well-known brands in the VR space, 3Glasses and ANTVR, are already using Hillcrest Labs’ BNO085 sensor module to provide their customers with a better VR experience.
