I am also working on a similar model of Modular approach.

?

But I am working on a concept of Plug-in modules. I have already created some of the modules which when ready will be plugged in a Base board (Motherboard) and interlinked without cables.

?

I share some of my Schematics with the group.

Hello Woolf,

I have Eagle layout files for the RF sections of the UbitX. I took a modular approach, so there are several circuit boards that you could make a UbitX or a single conversion design. I've been thinking about uploading them to the files section for some time but I just haven't done it. Here are a couple of pictures of the exciter section (single conversion). Let me know if you would like them and I get email them to you:
