- **baud_rate** (**Required**, int): The baud rate of the UART bus.
- **tx_pin** (*Optional*, :ref:`config-pin`): The pin to send data to from the ESP's perspective.
- **rx_pin** (*Optional*, :ref:`config-pin`): The pin to receive data on from the ESP's perspective.
- **data_bits** (*Optional*, int): The number of data bits used on the UART bus. Options: 5 to 8. Defaults to 8.
- **parity** (*Optional*): The parity used on the UART bus. Options: ``NONE``, ``EVEN``, ``ODD``. Defaults to ``NONE``.
- **stop_bits** (*Optional*, int): The number of stop bits to send. Options: 1, 2. Defaults to 1.
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID for this UART hub if you need multiple UART hubs.
