Seeed Studio XIAO RP2040 is a microcontroller using the Raspberry RP2040 chip. It runs at up to 133 MHz, is built with rich interfaces in a tiny thumb size, and fully supports Arduino, MicroPython, and CircuitPython.

The XIAO RP2040 is a development board of the Seeed Studio XIAO series. Like the Seeed Studio XIAO SAMD21, it is a compact board with a wide range of interfaces. The XIAO RP2040 is equipped with the Raspberry RP2040 chip (Dual-core ARM® Cortex® M0+) and has 2 MB of Flash on board.


  • 11 digital pins
  • 4 analog pins
  • 11 PWM Pins
  • 1 I2C interface
  • 1 UART interface
  • 1 SPI interface
  • 1 SWD Bonding pad interface

Some PINs have various functions, Moreover, XIAO RP2040 supports the USB-C interface which can supply power and download code. 1 Reset button, 1 BOOT button, 1 user-programmable RGB LED, 1 power LED, 2 status indicators, and 1 user LED are on board, allowing developers to debug their code very easily.

The XIAO RP2040 is very compact because all electronic components are soldered on the same board surface, which means you can easily solder the XIAO RP2040 to your own PCB. XIAO RP2040 is pin-compatible with Seeed Studio XIAO SAMD21, so XIAO RP2040 can be learned and developed using the Expansion board of Seeeduino XIAO.

Absolute Newest

Every time we commit new code to CircuitPython we automatically build binaries for each board and language. The binaries are stored on Amazon S3, organized by board, and then by language. These releases are even newer than the development release listed above. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.

Previous Versions of CircuitPython

All previous releases of CircuitPython are available for download from Amazon S3 through the button below. For very old releases, look in the OLD/ folder for each board. Release notes for each release are available at GitHub button below.

Older releases are useful for testing if you something appears to be broken in a newer release but used to work, or if you have older code that depends on features only available in an older release. Otherwise we recommend using the latest stable release.
