+=======================
+Adafruit Feather RP2040
+=======================
+
+The Feather RP2040 is a general purpose RP2040 board supplied by
+Adafruit.
+
+.. figure:: Feather.png
+ :align: center
+
+Features
+========
+
+* RP2040 microcontroller chip
+* Dual-core ARM Cortex M0+ processor, flexible clock running up to 133 MHz
+* 264kB of SRAM, and 8MB of on-board Flash memory
+* Castellated module allows soldering direct to carrier boards
+* USB Host and Device support via type C connector.
+* Low-power sleep and dormant modes
+* Drag & drop programming using mass storage over USB
+* 26 multi-function GPIO pins
+* 2× SPI, 2× I2C, 2× UART, 3× 12-bit ADC, 16× controllable PWM channels
+* Accurate clock and timer on-chip
+* Temperature sensor
+* Accelerated floating point libraries on-chip
+* 8 × Programmable IO (PIO) state machines for custom peripheral support
+* LiPoly Battery connector
+
+Serial Console
+==============
+
+By default a serial console appears on pins 14 (RX GPIO0) and pin 15
+(TX GPIO1). This console runs a 115200-8N1.
+
+The board can be configured to use the USB connection as the serial console.
+
+Buttons and LEDs
+================
+
+User LED controlled by GPIO13.
+
+A ws2812 (NeoPixel) smart RGB LED controlled by GPIO16.
+
+An LED (CHG LED) that indicates the charging status of
+connected LiPo cell.
+
+There is a BOOT button which if held down when power is first
+applied or the RESET button is pressed will cause the RP2040 to
+boot into program mode and appear as a storage device to
+a USB connecte . Saving a .UF2 file to this device will
+replace the Flash ROM contents on the RP2040.
+
+A RESET button that allows rebooting the board without disconnecting
+the power.

+26 VBUS Connected to USB +5V
+27 EN Pull to ground to turn off 3.3V regulator.
+28 VBAT Connected to LiPo battery 3.3V.
+===== ========== ==========
+
+The board has a STEMMA QT connector that is also connected to
+pins GPIO2 (I2C1 SDA) and GPIO3 (I2C1 SDA).
+
+The board has a two pin JST PH socket that accepts a single 3.3V
+LiPo cell. The cell connected to this port can be charged by
+connecting the board to a USB power supply.
+
+There are solder pads on the board that allow the addition of
+a 10-pin serial debug (SWD) connector.
+
+Power Supply
+============
+
+The Raspberry Pi Pico can be powered via the USB connector,
+or by supplying +5V to pin 39. The board had a diode that prevents
+power from pin 39 from flowing back to the USB socket, although
+the socket can be power via pin 30.
+
+The Raspberry Pi Pico chip run on 3.3 volts. This is supplied
+by an onboard voltage regulator. This regulator can be disabled
+by pulling pin 37 to ground.
+
+The regulator can run in two modes. By default the regulator runs
+in PFM mode which provides the best efficiency, but may be
+switched to PWM mode for improved ripple by outputting a one
+on GPIO23.

+Power Supply
+============
+
+The Raspberry Pi Pico can be powered via the USB connector,
+or by supplying +5V to pin 39. The board had a diode that prevents
+power from pin 39 from flowing back to the USB socket, although
+the socket can be power via pin 30.
+
+The Raspberry Pi Pico chip run on 3.3 volts. This is supplied
+by an onboard voltage regulator. This regulator can be disabled
+by pulling pin 37 to ground.
+
+The regulator can run in two modes. By default the regulator runs
+in PFM mode which provides the best efficiency, but may be
+switched to PWM mode for improved ripple by outputting a one
+on GPIO23.

+==================
+
+The following list indicates peripherals currently supported in NuttX:
+
+============== =====
+Peripheral Notes
+============== =====
+GPIO See Supported Boards documentation for available pins.
+UART GPIO 0 (UART0 TX) and GPIO 1 (UART0 RX) are used for the console.
+I2C
+SPI
+DMAC
+PWM
+USB
+PIO RP2040 Programmable I/O
+IRQs
+DMA
+ws2812 Smart pixels (e.g. Neopixel)
+Flash ROM Boot
+SRAM Boot If Pico SDK is available a nuttx.uf2 file will be created
+BMP180 Requires I2C0
+INA219 Requires I2C0
+============== =====
+
+The Pico Display Pack (ST7789 LCD) and Pico Audio Pack (PCM5100A I2S DAC) are
+also available.
+
+Installation
+============
+
+1. Download Raspberry Pi Pico SDK::
+
+ git clone -b 1.1.2 https://github.com/raspberrypi/pico-sdk.git
+
+2. Set PICO_SDK_PATH environment variable::
+
+ export PICO_SDK_PATH=<absolute_path_to_pico-sdk_directory>
+
+3. Download NuttX and the companion applications. These must both be
+ contained in the same directory::
+
+ git clone https://github.com/apache/incubator-nuttx.git nuttx
+ git clone https://github.com/apache/incubator-nuttx-apps.git apps
+
+Building NuttX
+==============
+
+1. Change to NuttX directory::
+
+ cd nuttx
+
+2. Select a configuration. The available configurations
+ can be listed with the command::
+
+ ./tools/configure.sh -L
+
+3. Load the selected configuration.::
+
+ make distclean
+ ./tools/configure.sh <selected_configuration>
+
+4. Modify the configuration as needed (optional)::
+
+ make menuconfig
+
+5. Build NuttX::
+
+ make
+
+Programming
+============
+
+Programming using BOOTSEL
+-------------------------
+
+Connect board to USB port while pressing BOOTSEL.
+The board will be detected as USB Mass Storage Device.
+Then copy "nuttx.uf2" into the device.
+(Same manner as the standard Pico SDK applications installation.)
+
+Programming using SDB
+---------------------
+
+Most (but no all) RP2040 boards provide a serial (SDB) debug port.
+The "nuttx" ELF file can be uploaded with an appropriate SDB programmer
+module and companion software.
+
+Running NuttX
+=============
+
+Most builds provide access to the console via UART0. To access this
+GPIO 0 and 1 pins must be connected to the device such as USB-serial converter.
+
+The `usbnsh` configuration provides the console access by USB CDC/ACM serial
+devcice. The console is available by using a terminal software on the USB host.

+<p>The board has a STEMMA QT connector that is also connected to
+pins GPIO2 (I2C1 SDA) and GPIO3 (I2C1 SDA).</p>
+<p>The board has a two pin JST PH socket that accepts a single 3.3V
+LiPo cell. The cell connected to this port can be charged by
+connecting the board to a USB power supply.</p>
+<p>There are solder pads on the board that allow the addition of
+a 10-pin serial debug (SWD) connector.</p>

+<div class="section" id="power-supply">
+<h2>Power Supply<a class="headerlink" href="#power-supply" title="Permalink to this headline">¶</a></h2>
+<p>The Raspberry Pi Pico can be powered via the USB connector,
+or by supplying +5V to pin 39. The board had a diode that prevents
+power from pin 39 from flowing back to the USB socket, although
+the socket can be power via pin 30.</p>
+<p>The Raspberry Pi Pico chip run on 3.3 volts. This is supplied
+by an onboard voltage regulator. This regulator can be disabled
+by pulling pin 37 to ground.</p>
+<p>The regulator can run in two modes. By default the regulator runs
+in PFM mode which provides the best efficiency, but may be
+switched to PWM mode for improved ripple by outputting a one
+on GPIO23.</p>

+<h2>Power Supply<a class="headerlink" href="#power-supply" title="Permalink to this headline">¶</a></h2>
+<p>The Raspberry Pi Pico can be powered via the USB connector,
+or by supplying +5V to pin 39. The board had a diode that prevents
+power from pin 39 from flowing back to the USB socket, although
+the socket can be power via pin 30.</p>
+<p>The Raspberry Pi Pico chip run on 3.3 volts. This is supplied
+by an onboard voltage regulator. This regulator can be disabled
+by pulling pin 37 to ground.</p>
+<p>The regulator can run in two modes. By default the regulator runs
+in PFM mode which provides the best efficiency, but may be
+switched to PWM mode for improved ripple by outputting a one
+on GPIO23.</p>
