+IMU (`inertial measurement unit <https://en.wikipedia.org/wiki/Inertial_measurement_unit>`__) node can be used to receive data
 from the IMU chip on the device. Our OAK devices use either:
 
 - `BNO085 <https://www.ceva-dsp.com/product/bno080-085/>`__ (`datasheet here <https://www.ceva-dsp.com/wp-content/uploads/2019/10/BNO080_085-Datasheet.pdf>`__) 9-axis sensor, combining accelerometer, gyroscope, and magnetometer. It also does sensor fusion on the (IMU) chip itself. We have efficiently integrated `this driver <https://github.com/hcrest/bno080-driver>`__ into the DepthAI.
