I have noticed that the revisions on the boards purchased from Smashtv differ greatly from the board layouts posted in the wiki and at UCapps.de. Where can I find the latest layouts so I can make my own boards if I should so choose?
thanks
you have already found the latest layouts.
SmashTV’s layouts are not well suited to home etching, and are not published.
Don’t confuse R and V - as in, R3 vs V3… different things entirely 
They aren’t revisions of the same boards, but different boards entirely.
