All schematics and pcb designs are finished now. But I will do several checks before I send the PCB's out for production. (I already found some mistakes, can you find them too ?)

Today I uploaded in the file section:

This info should be enough to understand the design.

I also posted the number of main components (327 relays). On the MEM pcb, I used BAW56 double-diodes because 1N4148 would cost me too much pcb area.
