I keep getting distracted from this. Plus work.
And I'm at the difficult point. It was looking more complex than I expected and my KiCAD skills aren't what they should be. I haven't read as much of datasheets as I need to to understand. Maybe I should ask someone? Dunno who.
I think I'll stick with the prototype for this thing. Sometime I'll take up a smaller project to figure out KiCAD. And then maybe come back to it?
Some other neat video stuff on Hackaday but not sure if anyone is directly going to a 40ish pin screen the way I was thinking.
