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?

    HDMI cables, with 19pins (I will use it in my next build), or flat cables, which you can find in different sizes and pin counts (I used some with 10 pins in my Rommana). Both types of connector and cables can be easily found in Aliexpress.

      Thank you. It was specifically the CAT6 I was Looking to use, as you can get an ultra thin patch cable, and it will clip in (so reduced risk of shorting the controller). Maybe I need to go without RGB? 😭
