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?

Ordered before I saw this :-/ Bet that’s ok. I can do a bit of a hark if needed. The 3 & 5 volt pins are right next to each other.
