  • 2MB of QSPI flash supporting XiP
  • Compatible with WS2812/Neopixel/SK6812 and APA102/Dotstar/SK9822 LEDs
  • Sturdy screw terminals for attaching your LED strip
  • USB-C connector for power and programming
  • Qw/ST (Qwiic/STEMMA QT) connector
  • Low side current sensing (accessible via ADC3)
  • Reset, BOOT and two user buttons (the BOOT button can also be used as a user button)
  • RGB LED

About the RP2040

Raspberry Pi’s RP2040 microcontroller is a dual core ARM Cortex M0+ running at up to 133Mhz. It bundles in 264kB of SRAM, 30 multifunction GPIO pins (including a four channel 12-bit ADC), a heap of standard peripherals (I2C, SPI, UART, PWM, clocks, etc), and USB support.

One very exciting feature of RP2040 is the programmable IOs which allow you to execute custom programs that can manipulate GPIO pins and transfer data between peripherals - they can offload tasks that require high data transfer rates or precise timing that traditionally would have required a lot of heavy lifting from the CPU.

CircuitPython 7.0.0-rc.3

This is the latest unstable release of CircuitPython that will work with the Plasma 2040.

Unstable builds have the latest features but are more likely to have critical bugs.

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. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.

Past Releases

All previous releases are listed on GitHub, with release notes, and are available for download from Amazon S3. They are handy for testing, but otherwise we recommend using the latest stable release. Some older GitHub release pages include the same binaries for downloading. But we have discontinued including binaries as assets on newer release pages because of the large number of files for each release.
