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

Cable reduction help (self.ergomechkeyboards)

Hi all,

I have an idea in my head, but I’m a cable short, and looking for suggestions.

24-key split-ortho (2 keys per finger, where you press both top and bottom keys simultaneously to get the home row key), with per-key RGB and OLED display on the left side. But…

I’d like to run this off a single BlackPill controller on the left hand side, and use a CAT6 cable to bridge the two sides.

CAT6 has 4 twisted pairs, so 8 cables. If I run a 4x3 matrix then that’s 7 cables. Plus another for the VCC for the RGB. But then no more for the DIN/DOUT for RGB. GND should be fine as I can earth the right hand side separately, but I’m missing a cable if I want RGB.

Are there any suggestions on how I might be able to get around my challenge?

I’ve taken a look, and it seems that this might be exactly what I was looking for. Frees three cables up for the RGB.
