If there is one thing Adafruit is known for, its mega-blinky-fun-rainbow-LEDs. [We just love sticking NeoPixels anywhere and everywhere](https://www.adafruit.com/category/168). When we saw the new 'PIO' peripheral on[ the RP2040 from Raspberry Pi](https://www.adafruit.com/category/875), we just knew it would be perfect for driving large quantities of NeoPixels. So we created this board, the **Adafruit Feather RP2040 SCORPIO**, designed specifically for NeoPixel (WS2812) driving but also good for various other PIO-based projects that want to take advantage of the Feather pinout with 8 separate consecutive outputs (or inputs). - If there is one thing Adafruit is known for, its mega-blinky-fun-rainbow-LEDs.

[The RP2040 PIO state machine](https://learn.adafruit.com/intro-to-rp2040-pio-with-circuitpython) is perfect for LED driving: it can generate perfect waveforms, with up to 8 outputs concurrently, all through DMA. That means that you don't need to use any processor time to bit-bang-out the LED data. Just set up the buffer and tell the PIO peripheral to 'make it so' and it will shove that data to the 8 outputs without delay while your code can continue to read buttons, play music, run CircuitPython - whatever you like!
