Script UART communication
=========================

This example uses :ref:`Script` node for `UART communication <https://en.wikipedia.org/wiki/Universal_asynchronous_receiver-transmitter>`__. Note that OAK
cameras don't have UART pins easily disposed, and we soldered wires on `OAK-FFC-4P <https://docs.luxonis.com/projects/hardware/en/latest/pages/DD2090.html>`__
to expose UART pins.

.. note::

    This should only be run on OAK-FFC-4P, as other OAK cameras might have different GPIO configuration.
