Here is our RP2040 Feather with 8 x 5V buffered outputs for addressable LEDs #comingsoon … help name it :)
The niftiest peripheral on the RP2040 chip is called ‘pio’ – a programmable state machine that can handle streams of bitbang data. 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. 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. it uses every single pin on the RP2040 and should work great for neopixels, dotstars, etc. we still need a name for this board so we’ll be contemplating that while pondering our orb this weekend.
Names with octo and all that are getting tossed around, so if ya have a great idea/name for it, let us know.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
