Names with octo and all that are getting tossed around, so if ya have a great idea/name for it, let us know. we still need a name for this board so we’ll be contemplating that while pondering our orb this weekend. it uses every single pin on the RP2040 and should work great for neopixels, dotstars, etc. this feather takes our fab RP2040 feather and adds a vertical JST SH, then removes the SWD header, enshrinkens a bunch of parts, to make room for an 8 pin header that is 5V-shifted-and-buffered with an 74AHCT245 with the 8 GPIO in consecutive order on the port. One of the first demos for pio is to drive NeoPixels (a.k.a ws2812 addressable LEDs) since they use a single pulse-width encoding scheme which often requires a lot of bitbanging or clever timer+DMA. The niftiest peripheral on the RP2040 chip is called ‘pio’ – a programmable state machine that can handle streams of bitbang data.
