    # Example configuration entry
    pca9685:
      - id: 'pca9685_hub1'
        frequency: 500

    # Individual outputs
    output:
      - platform: pca9685
        id: 'pca9685_output1'
        pca9685_id: 'pca9685_hub1'
        channel: 0

Configuration variables:
~~~~~~~~~~~~~~~~~~~~~~~~

-  **id** (**Required**, `id </esphomeyaml/configuration-types.html#id>`__): The id to use for this output component.
-  **channel** (**Required**, int): Chose the channel of the PCA9685 of
   this output component. Must be in range from 0 to 15.
-  All other options from
   `Output </esphomeyaml/components/output/index.html#base-output-configuration>`__.
- **pca9685_id** (*Optional* `id </esphomeyaml/configuration-types.html#id>`__): Manually specify the ID of the `PCA9685 hub </esphomeyaml/components/pca9685.html`__. Use this if you have multiple PCA9685s you want to use at the same time.
