Hi Todd, I can take a look and perhaps even update the KiCad files. Bob has a lot of great ideas for improvements. I can take apart my systems and measure the hole placements. If the backplane has to become a little wider, I believe it's worth the extra expense. Please give me until the weekend to bring this project to the drawing board. Are the Kicad files on the wiki site?
