I have the SK6812 RGBNW and after connecting them to pin 19 - GPIO 10 (https://pinout.xyz/pinout/spi) it seems to be working fine, but I have couple of issues:
- first led is always the same colour and is not changing with the rest
- the config is a bit flaky and sometimes I need to switch to a different LED chip and back to make it work (I use ws2812spi)
- in case of RPi3 and RPi4 I think you need a level shifter 3.3v to 5v - in my case it was blinking like crazy and was not useful
- even with a level shifter, I have occasional blinking of the LEDs that I do not know what might be a reason for (maybe my soldering, but I doubt it)
This was tested on version alpha 8 & 9 so should not be a software issue.
Could you already fix your issues and how?
I'm looking for a new LED strip and want to know if this strip is good enough.
