A derivative of the 2040rmie drop-in PCB for the 40rmie family of keyboards using 40s modifiers.
The original 40s-2040rmie USB port and rotary encoder position were slightly off. This probably didn't matter for the acrylic or 3d printed cases, but for the 40rmie LX the tolerances seem to have gotten a bit tighter, so I adjusted them to the correct position.
Additionally I simplified the layout options to only use the ones I am interested in. It should be pretty straightforward to add additional e.g. bottom-row layouts though.
I have tested this in my 40rmie LX using the no-blockers, no-encoders layout.
There should be no problems using the other layouts as I put quite a bit of effort into checking the component positions matched the original PCB. However Order at your own risk!
