Accelerometer, Gyroscope, Magnetometer, 9 Axis Sensor I2C, SPI, UART Output
The BNO085 is a high-performance 9-axis absolute orientation sensor system-in-package (SiP) that integrates a 3-axis accelerometer, 3-axis gyroscope, 3-axis magnetometer, and a low-power ARM Cortex-M0+ microcontroller running CEVA/Hillcrest SH-2 sensor fusion firmware. It provides accurate real-time orientation, motion tracking, and activity detection while offloading complex sensor fusion calculations from the host processor. The device is widely used in robotics, AR/VR systems, wearables, drones, IoT devices, and navigation applications.
