So I am trying to design a full size(108 key) board with per key rgb but I have a few issues I am running into in regards to what LEDs to use and how to mount them under a matias switch via a cutout and soldering them inside the slot. As well I was thinking of maybe doing some under glow as well, yes I know it may be a lot but I want to at least have one in the collection and will just use this at home anyways.
Also I was planning on using the Teensy++ 2.0 as it gives me a little more freedom on the pinout, could actually use the Teensy 2.0 as I was able to make a matrix that only needed 24 pins for a full size but I prefer not to be limited in case I want to add on before I finish the design phase.
I have done quite a bit of searching over the past couple days to no avail, so here are the questions I have:
1) What are the big differences between them? Pros and cons?
2) There are two main versions of the SK6812, RGB and RGBW, is it possible to use the RGBW or is that not supported? I would prefer to use those as the white would be way more accurate.
3) What needs to be changed, if anything, in QMK to use the SK6812? And any info on how to do it myself without the need of kbfirmware.com would be nice so I can do some custom bits.
4) How do most people power this many LEDs? A power brick plugged in to the board? I want to be able to run all at full brightness, even if I may not always have it set that way.
5) I read in another thread that the is a 10 μf limit for capacitors on the LEDs, not sure why this is or how to work around it if I have 108+ leds...
I recently found a 3535 package SK6812 RGB and would love to be able to use that as it would use a smaller cutout in the board and make life a bit easier for routing.
