+========================
+Seeed Studio Xiao RP2040
+========================
+
+The `Seeed Studio Xiao RP2040 <https://wiki.seeedstudio.com/XIAO-RP2040/>`_ is
a general purpose board supplied by
+Seeed Studio and it is compatible with the Raspberry Pi RP2040 ecosystem as
they share the same RP2040 chip.
+
+.. figure:: seeed-xiao-rp2040.jpg
+ :align: center
+
+Features
+========
+
+* RP2040 microcontroller chip
+* Dual-core ARM Cortex M0+ processor, flexible clock running up to 133 MHz
+* 264KB of SRAM, and 2MB of onboard Flash memory
+* 11 digital pins, 4 analog pins, 11 PWM Pins
+* 1 I2C interface, 1 UART interface, 1 SPI interface, 1 SWD Bonding pad
interface
+* USB Type-C interface
+* 1 user LED, 1 power LED, two LEDs for serial port downloading, 1 RGB LED
+* 1 RESET button, 1 BOOT button
+
+Serial Console
+==============
+
+By default a serial console appears on pins 6 (TX GPIO0) and pin 7
+(RX GPIO1). This console runs a 115200-8N1.
+The board can be configured to use the USB connection as the serial console.
+
+LEDs
+====
+
+There are 2 LEDs available for user:
+
+- A RGB LED connected to GPIO16 (PIN_LED_G), GPIO17 (PIN_LED_R), GPIO25
(PIN_LED_B).
+- A NeoPixel RGB LED connected to GPIO11 (NEOPIXEL_POWER) and GPIO12
(PIN_NEOPIXEL).
+
+Buttons
+=======
+
+There are 2 buttons available:
+
+A RESET button and a BOOT button, which if held down when power is first
+applied to the board, will cause the RP2040 to boot into programming
+mode and appear as a storage device to a computer connected via USB.
+Saving a .UF2 file to this device will replace the Flash ROM contents
+on the RP2040.
+
+
+Pin Mapping
+===========
+Pads numbered anticlockwise from USB connector.
+
+===== ========== ==========
+Pad Signal Notes
+===== ========== ==========
+0 GPI26 D0/A0
+1 GPI27 D1/A1
+2 GPI28 D2/A2
+3 GPI29 D3/A3
+4 GPIO6 D4/SDA
+5 GPIO7 D5/SCL
+6 GPIO0 Default TX for UART0 serial console
+7 GPIO1 Default RX for UART1 serial console/CSn
+8 GPIO2 D8/SCK
+9 GPIO3 D10/MOSI
+10 GPIO4 D9/MicroSD
+11 3V3 Power output to peripherals
+12 Ground
+13 VIN +5V Supply to board
+===== ========== ==========
+
+Power Supply
+============
+For general I/O pins:
+
+Working voltage of MCU is 3.3V. Voltage input connected to general I/O pins
+may cause chip damage if it' higher than 3.3V.
+
+For power supply pins:
+
+The built-in DC-DC converter circuit able to change 5V voltage into 3.3V allows
+to power the device with a 5V supply via VIN-PIN and via the USB connector.
+
+Configurations
+==============
+
+nsh
+---
+
+Basic NuttShell configuration (console enabled in UART0, at 115200 bps).
