    The split configuration would make it easier to repair, and the 
control boards can be plugged end to end. You can eliminate the jumpers 
on the headers with a drop of solder on the underside of the boards.

    If a relay board or controller board fails, it will be much cheaper 
to repair. You can buy ready made 40 conductor cables with single Dupont 
contacts on Ebay to harness them together. I remove the single contact 
shells and replace them with a single, with the proper number of 
positions. That way, my projects look a lot neater than the typical wad 
of individual wires.

    I may use a pair of these boards in a custom, multiple iron 
soldering station that I'm building.
