which has the nasty details of the 5V 'tolerance' of the RP2040.

The TL'DR is that in practical terms, the 5V tolerance is like the cake, mostly a lie.

Well, I wouldn't quite go that far. I have used the Rp2040 in circuits where I didn't have room for a level shifter and they have been fine so far. It helps that a lot of old computers seem to have run their 5V rails at just under 5V too.
