    Duotriginti, 32-channel neopixel driver for Teensy 4.1

    I've been using OctoWS2811 for my xmas display for years. Last year I ran 8000 LEDs from two OctoWS2811 adapters, which has worked great. ( for more information)
    This year, I'm planning to go for 10000 lights, and I noticed that the OctoWS2811 library now supports Teensy4.1, potentially driving all the digital outputs in one go, which seems nicer than having a whole bunch of OctoWS2811 adapters running in parallel. Also, the USB speed is starting to become a problem with the OctoWS2811 adapters. So I went ahead and designed a quad-octows2811 adapter which I call DuotrigintiWS. It's fully capable of running 32000 LEDs at 30 fps. (Or 16000 LEDs at 60 fps)

    Here is a first test video showing it in action.

    I will be sharing full details of how to build these on my website, including kicad sources and BOM, but that will take a little while.
    For anybody who is really impatient, here is an oshpark link for the PCB:

    This looks very interesting and am looking forward to the details!

    BTW, the video you included is unavailable as it is private.
