+=========================
+Seeed Studio XIAO ESP32S3
+=========================
+
+The `Seeed Studio XIAO ESP32S3
<https://wiki.seeedstudio.com/xiao_esp32s3_getting_started/>`_ is a general
purpose board supplied by
+Seeed Studio and it is compatible with the Espressif ESP32S3 ecosystem,
sharing the same MCU as ESP32-S3-DevKitC.
+
+.. figure:: xiao-esp32s3.jpg
+ :align: center
+
+Features
+========
+
+* ESP32-S3R8 Xtensa LX7 dual-core, 32-bit processor that operates at up to 240
MHz
+* On-chip 8M PSRAM & 8MB Flash
+* USB Type-C interface
+* Wireless: Complete 2.4GHz Wi-Fi subsystem;
+* BLE: Bluetooth 5.0, Bluetooth mesh
+* 1x UART, 1x I2C, 1x I2S, 1x SPI, 11x GPIOs (PWM), 9x ADC
+* 1 user LED, 1 power LED
+* 1 RESET button, 1 BOOT button
+
+NSH Console
+===========
+
+The NuttShell (NSH) console is available over USB using the CDC/ACM
+serial interface. To access the console, connect via a terminal emulator
+at 115200 baud, 8 data bits, no parity, and 1 stop bit (115200-8N1).
+
+User LED
+========
+
+The USER LED, a yellow LED located on the XIAO ESP32S3 board, is
+connected to GPIO21 as indicated in the board's schematic. This LED
+can be controlled through NuttX by configuring GPIO21 as an output
+and toggling its state.
+
+Buttons
+=======
+
+The RESET and BOOT buttons can be used to enter "Bootloader" mode by
+press and hold the BOOT key while powering up and then press the RESET key
once.
+
+Pin Mapping
+===========
+Pads numbered anticlockwise from USB connector.
+
+===== ========== ==========
+Pad Signal Notes
+===== ========== ==========
+0 GPIO01 D0/A0
+1 GPIO02 D1/A1
+2 GPIO03 D2/A2
+3 GPIO04 D3/A3
+4 GPIO05 D4/SDA
+5 GPIO06 D5/SCL
+6 GPIO43 D6/Default TX for UART0 serial console
+7 GPIO44 D7/Default RX for UART0 serial console
+8 GPIO07 D8/SCK
+9 GPIO08 D9/MISO
+10 GPIO09 D10/MOSI
+11 3V3 Power output to peripherals
+12 Ground
+13 VIN +5V Supply to board
+===== ========== ==========
+
+Power Supply
+============
+The working voltage of the MCU is 3.3V. Voltage input connected to
+general I/O pins may cause chip damage if it’s higher than 3.3V.
+
+Installation
+============
+
+1. Configure and build NuttX:
+
+.. code-block:: console
+
+ $ git clone https://github.com/apache/nuttx.git nuttx
+ $ git clone https://github.com/apache/nuttx-apps.git apps
+ $ cd nuttx
+ $ make distclean
+ $ ./tools/configure.sh xiao-esp32s3:usbnsh
+ $ make V=1
+
+2. Connect the Seeed Studio XIAO ESP32S3, and enter "Bootloader" mode,
+then, flash the ``nuttx.hex`` file using ``esptool``:
+(https://docs.espressif.com/projects/esptool/en/latest/esp32/)
+
+Example command:
+
+.. code-block:: bash
+
+ make flash ESPTOOL_PORT=/dev/ttyACM0 ESPTOOL_BINDIR=./
+
+
+Configurations
+==============
+
+usbnsh
+------
+Basic NuttShell configuration using CDC/ACM serial (console enabled in USB
Port,
+at 115200 bps).
+
+.. code-block:: console

+This configuration enabled NuttShell via USB and enabled led and gpio examples:
+
+Testing leds:

-<p>The internal USB JTAG SERIAL Device, by default, is used as serial console.
-It is normally detected by Linux host as a USB CDC/ACM serial device.</p>
-<p>It will show up as /dev/ttyACM[n] where [n] will probably be 0.</p>
-<p>You can use minicom with /dev/ttyACM0 port at 9600 8n1 or picocom this
way:</p>

-<p>There are two buttons labeled BOOT and RST. The RST button is not available
-to software. It pulls the chip enable line that doubles as a reset line.</p>
-<p>The BOOT button is connected to IO0. On reset it is used as a strapping
-pin to determine whether the chip boots normally or into the serial
-bootloader. After reset, however, the BOOT button can be used for software
-input.</p>
