Hi Luke,

I read through your instructions and looked and the files that are needed and I
think I understand how this will be done. However, I'm getting stuck currently
on not being able to find a simple pinout diagram on the ulx3s85f. There are
schematics for it which I can't quite make sense of, and there's the exact
diagram I'm looking for... but it's for the esp32 module not the ulx3s pcb :(

Would this info be in the constraints file?

And/or the schematic diagrams?

There is a pinout csv file but it has about 1000 entries and looks like it's
out of date as it's from 2015. I'm entirely out of my depth here.

Sorry, I need some significant help here as this is currently melting my brain.
