So something like this then. 178mm wide, could be a little narrower, 50m tall.Trying to hold to <200mm x 50mm for board size price break.I do custom boards, custom shields.What are you after besides the platform to mount stuff onto?
Rotating - sounds good, would make board really long. I think also less practical for power headers. Maybe just turn the outer ones?.I could see making one of the three a arduino clone.Or at least alloeing for it to be populated as one.
