I have three different kinds of keyboards. Regular, Alice and split ergo with columnar stagger. It always takes a little while to get back to speed when I switch boards. But I think that the layouts are different enough so that a distinct muscle memory forms for each one. I guess that the most important thing is that you should be fairly proficient with touch typing on a regular board before trying a different layout. If you are still in the phase of learning, I imagine that it gets really frustrating.

I am using Elite Pi microcontrollers (RP2040)

Thanks! I can give you the files so you can print it yourself 😉

It feels pretty good and the sound is actually okay too. Maybe next time I’ll try it with a PCB. One advantage of hand wiring is that the RGB also shows through the top. That wasn’t really intentional, but it looks nice. A PCB would have blocked the light and I would need to add per key LEDs for the same effect.

Thanks. Yep, cable is DIY
