Ergonomic, split and other weird keyboards
Rules
Keep it ergo
Posts must be of/about keyboards that have a clear delineation between the left and right halves of the keyboard, column stagger, or both. This includes one-handed (one half doesn't exist, what clearer delineation is that!?)
i.e. no regular non-split¹ row-stagger and no non-split¹ ortholinear²
¹ split meaning a separation of the halves, whether fixed in place or entirely separate, both are fine.
² ortholinear meaning keys layed out in a grid

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
Before you go charging full speed ahead, you need to look up what the logic voltage on the blackpill is. I've never used one, so you'll have to check that for yourself.
If the blackpill's high voltage is 3.3v, then an RGB running at 5v will likely not recognize 3.3v as high (or as a binary 1 if that's easier to think about).
There are two ways to get around this, either power the RGBs from 3v which is out of spec but will work (they will be dimmer though, and again this is out of spec), or shift the blackpill's logic level to a higher voltage. You can use a diode to accomplish this, with this fiendishly clever hack.
If you need to use either of the above approaches, probably a good idea to breadboard it first before shelling out for the PCBs
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.
