Beautiful!
2.54 is correct I believe,
Those nets look exactly like I visualized them.
The image is kinda small on my phone, and I am unfamiliar with eagle is that all connected? Do you intend on finishing this? Do you consider this just a draft or something you can tweak to compleetion?
I was imagining issues with too many vias everywhere to connect to the smd pads. I had intended on routing on the internal layers as much as possible but I suppose routing on the top and bottom would save a lot of vias for smd setup. 🤔
How do your floods look? Or will you need extra layers for it?
Being that the problem is so geometric, I was hoping for a symmetric solution a pattern to the routing ya know.
I agree that smd looks like the way to go from a pcb design standpoint
I also agree that maybe routing all of them and forgetting about power floods may be an option.
I would at the very least like to flood grond though. Perhaps there is a ground pin in a location that is equal on all 4 orientations
