Yes, this is first version.
I made 2 boards because of i didnt know, how it can works - good or not good, I checked only repeater board and only backplane board and both. And I can use repeater board for testing any one interfaces outside QL.
For vertical version one board - very good idea, for horisontal version - anyway need additional perpendicular board.
