Pnikolaj,
Very sorry to hear about the board. If I had a spare I'd give it to you.
Schematics and wiring diagrams should never be used to determine physical orientation/location of connectors. Typically the silkcreen (overlay) on physical PCB would have a pin 1 indicator but I didn't have the room
An overlay drawing (like I included in the assembly instructions)or pin 1's called out on a picture of finished assembly are the next best thing.
I'll add the overlay to the manual right after wiring diagram. On wiring diagram I'll add note to reference overlay for pinout orientation. I'll make it part of package for version 1.4 release.
