Device
======

Device represents an `OAK camera <https://docs.luxonis.com/projects/hardware/en/latest/>`__. On all of our devices there's a powerful vision processing unit
(**VPU**), called `Myriad X <https://www.intel.com/content/www/us/en/products/details/processors/movidius-vpu.html>`__.
The VPU is optimized for performing AI inference algorithms and for processing sensory inputs (eg. calculating stereo disparity from two cameras).

Here are known camera limitations for the Myriad X:
Here are known camera limitations for the `RVC2 <https://docs.luxonis.com/projects/hardware/en/latest/pages/rvc/rvc2.html#rvc2>`__:

- **ISP can process about 600 MP/s**, and about **500 MP/s** when the pipeline is also running NNs and video encoder in parallel
- **3A algorithms** can process about **200..250 FPS overall** (for all camera streams). This is a current limitation of our implementation, and we have plans for a workaround to run 3A algorithms on every Xth frame, no ETA yet

IMU

IMU (`intertial 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 DepthAI devices use `BNO085 <https://www.ceva-dsp.com/product/bno080-085/>`__ 9-axis sensor (`datasheet here <https://www.ceva-dsp.com/wp-content/uploads/2019/10/BNO080_085-Datasheet.pdf>`__)
