Comment on Biqu B1 SKR V1.4 mainboard to SKR MINI E3 V3?

Well. Why would you want to do that?
In the end, choose the board that has the features you need. Software is the same anyway.
With Klipper you can even combine multiple boards to get the features you want.

Suspected that the SKR v1.4 original motherboard died (Hotend not heating), so advanced to the SKR MINI v3 + a Raspberry PI for Klipper.
I’m looking for “printer.cfg” that matches this setup…

The printer.cfg is highly dependent on your setup. For reference you can look at the example config for the SKR mini e3 v3: github.com/…/generic-bigtreetech-skr-mini-e3-v3.0…

Thanks. I’ve already used this one.
In the config file, some pins are named like “PB0”, but other have a “!” in front, like “!PB1”, and other a “^”, like “^PC2”. What are the “!” and “^” for?
What’s the difference between a “PB0” and a “PC11”.

An exclamation mark (!) inverts a pin. The other symbol (^) enables a pull up resistor on a pin, which is needed for things like endstops or buttons. These can also be combined.
PB0 is just the name of one pin. PC0 would be a completely different pin.
Different Microcontrollers have different naming conventions, that is why you sometimes see names like PB10 and on other controllers it might be GPIO10.
