This connector lets you add multiple SAOs to one host port in multiple directions with 90 degree options as well. Inspired by the edge connector footprint my brother Andy created for his SAO Demo Controller. I was going for the K'Nex toy vibe.
The distance between parallel flat surfaces is 1.00".

I am a complete noob when it comes to board design. My recently acquired "enough to be dangerous" skillset with KiCad has me exploring. When it came time to route this mess I tried the FreeRouting plug-in to route the traces for me. It was fun to watch it work solving the puzzle.
It's not pretty and I am sure real board designers are cringing right now but it saved me hours of clunking around to do it.
