Hello, I really like this project and also working on a fork that will use the Redragon low profile switch instead.

You stated in your reddit post that v0.2 will solve the usb placement problem, how would it look like ?

Hello.

There is a lot of extra empty space in the 100x100 rectangle (green) which could be used for an extra break-off part which would go between the two sides.
This would solve a couple of things:

  • It could use more pins for better stability, especially because of having more than one column
  • as you have two of these per keyboard, you could use both, one over and one under the pcb for even more stability
  • the extra wire and the jumper pad wouldn't be necessary as the controller could be routed properly on this extra board
  • but most importantly it would increase the distance between the two halves, therefore there would be enough space for the USB

One big disadvantage is that JLCPCB could recognize this as two designs and charge extra for it.

Here's what I imagined:

That’s a brilliant.
I’m wondering if we could route some open wires that don’t actually serve any purpose to the breakout part, just to trick them into thinking they’re part of the thumb cluster. It's similar to how the Corne 5x6 layout can be broken down into a 5x5 layout. The Corne uses M3 screw holes as a break point for that.

Yes! Routing some wires there could make it easier to argue that it's part of the same design.
