+pw_digital_io_rp2040
+--------------------
+``pw_digital_io_rp2040`` implements the :ref:`module-pw_digital_io` interface using
+the `Raspberry Pi Pico SDK <https://github.com/raspberrypi/pico-sdk/>`_.
+
+Setup
+=====
+Use of this module requires setting up the Pico SDK for use with Pigweed. Follow
+the steps in :ref:`target-raspberry-pi-pico` to get setup.
+
+Examples
+========
+Use ``pw::digital_io::Rp2040DigitalIn`` and
+``pw::digital_io::Rp2040DigitalInOut`` classes to control GPIO pins.
+
+Example code to use GPIO pins:
+
+.. code-block:: cpp
+
+   #include "pw_digital_io_rp2040/digital_io.h"
+
+   using pw::digital_io::Rp2040DigitalIn;
+   using pw::digital_io::Rp2040DigitalInOut;
+
+   Rp2040DigitalInOut out(/*gpio_pin=*/ 15);
+   out.Enable();
+   out.SetState(pw::digital_io::State::kInactive);
+
+   Rp2040DigitalIn in(/*gpio_pin=*/ 16);
+   in.Enable();
+   auto state = in.GetState();
