WS2812B / SK6812

[DonnyD]

I am planning creating pcb prototype with rgb per key lighting (used as under glow). I will be using https://kbfirmware.com/ for firmware. In settings, you can choose WS2812B leds number, but can it support SK6812 3535 ? On this https://beta.docs.qmk.fm/for-makers-and-modders/ws2812_driver page it sais it supports it, but firmware builder it doeasnt. Does it support it ?

there are minimal configuration options in kbfirmware.com (it is fantastic for hand wired boards)
to get more out of QMK or fine tune exactly what you need, create a build environment, clone, edit & build your firmware from the source at https://github.com/qmk/qmk_firmware
documentation site  https://docs.qmk.fm/#/

I am building 5x5 prototype based on corne keyboard wich uses sk6812 leds. So i can use sk6812, but with custom firmware, right ? That helped a lot. It seems a lot of fine tuning, but i think i can get trough it. I tried modifying XD96 firmware to support more than 32 leds and get them brighter (50/255 by default), but failed. Only with https://kai.tkg.io/ managed to get full brightness. Either way, thanks for helpful info. Also, with custom i could make each key light up in my programmed color ?

SK6812 is a direct clone of WS2812B - the pinout and specifications are exactly the same (except for one weird use case that doesn't apply). You can use them interchangably.

@DonnyD - yes, TMK will work fine too. both are forks of the same project. about the rest of the rgb questions... i can't help you. don't have any experience with them. there seems to be a number of different ways to do it depending on what your goals are.
