Gen7 Endstop 1.0/1.1 is the intitial version in the development of Gen7 Endstop. Circuitry was close to the one of RepRap's Generation 3 Electronics, but it was redesigned for DIY-ablility of the PCB.
For the most recent version, see Gen7 Endstop 1.3.1.
As this is no longer the newest version and is based on a part no longer available, you're pretty much on your own to make one. Best bet is to look up the releases folder of the release-1.1 branch on the Git repository.
Traumflug can do custom PCBs quickly, so if you offer him a beer or something, chances are good to get a couple of boards.
