I’m planning on building a custom keyboard with 24 keys running of a BlackPill. It’ll have OLED and RGB.
My question: the BlackPill has 3v and 5v pins. Which should I use for what?

Your best bet would be to look at the datasheets for the OLED or RBGs you want to use. I think most RGBs that are addressable that are commonly used are 5v
Found it, thank you!
RGB=5v OLED=3v
