Swathe everything in rainbows with this all-in-one, USB-C powered controller for WS2812/Neopixel and APA102/Dotstar addressable LED strips, with RP2040 in the driving seat - just perfect for whipping up some custom mood lighting.

Features

  • Powered by RP2040 (Dual Arm Cortex M0+ running at up to 133Mhz with 264kB of SRAM)
  • 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.

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.
