+RP2040 PIO LED Strip
+====================
+
+.. seo::
+    :description: Instructions for setting up addressable lights like NEOPIXEL on an RP2040 using the PIO peripheral.
+    :image: color_lens.svg
+
+This is a component using the RP2040 PIO peripheral to drive most addressable LED strips.
+
+.. code-block:: yaml
+
+    light:
+  - platform: rp2040_pio_led_strip
+        name: led_strip
+        id: led_strip
+        pin: GPIO13
+        num_leds: 10
+        pio: 0
+        rgb_order: GRB
+        chipset: WS2812B
+
+Configuration variables
+-----------------------
+
+- **pin** (**Required**, :ref:`config-pin`): The pin for the data line of the light.
+- **num_leds** (**Required**, int): The number of LEDs in the strip.
+- **pio** (**Required**, int): The PIO peripheral to use. If using multiple strips, you can use up to 4 strips per PIO. Must be one of ``0`` or ``1``.
+
+- **chipset** (**Required**, enum): The chipset to apply known timings from.
+    - ``WS2812``
+    - ``WS2812B``
+    - ``SK6812``
+    - ``SM16703``
+
+- **rgb_order** (**Required**, string): The RGB order of the strip.
+    - ``RGB``
+    - ``RBG``
+    - ``GRB``
+    - ``GBR``
+    - ``BGR``
+    - ``BRG``
+
+- **is_rgbw** (*Optional*, boolean): Set to ``true`` if the strip is RGBW. Defaults to ``false``.
+
+
+
+Manual Timings
+**************
+
+These can be used if you know the timings and your chipset is not set above. If you have a new specific chipset,
+please consider adding support to the codebase and add it to the list above.
+
+- **bit0_high** (*Optional*, :ref:`config-time`): The time to hold the data line high for a ``0`` bit.
+- **bit0_low** (*Optional*, :ref:`config-time`): The time to hold the data line low for a ``0`` bit.
+- **bit1_high** (*Optional*, :ref:`config-time`): The time to hold the data line high for a ``1`` bit.
+- **bit1_low** (*Optional*, :ref:`config-time`): The time to hold the data line low for a ``1`` bit.
