AFAIK the code behave the same... as its triggered and recovers from VIN, the processor does not actually "know" where the 5V power is from and if running the SBC and expect power loss recovery to work then the SBC having its own (battery backup) power would be a good idea

Best to start a thread in the forum to discuss what you want to do.

I’ve seen io3 used for the super pinda. Really you just need to match up the wires to the correct terminal and use the right pin names for that port in the config. If you have further questions, please start a forum thread. https://forum.duet3d.com/

RRF2 is no longer being updated. All work has moved to RRF3. 2.05.1 is the last RRF2 and is over a year old at this point. RRF3 is the recommended firmware going forward. There is unlikely to be any quality difference between them at this point, but there will be new features and bug fixes that will only be on RRF3.

The main difference is the increased flexibility of setup. The online config generator tool is able to produce a good starter config for RRF3, so there really isn’t that big a barrier to switching over.

Yes you could do that if you don’t mind the time it takes.

If you manually level the bed after creating the mesh, that mesh will no longer be valid, and you’ll have to probe again. If the bed is stable and doesn’t change tilt on it’s own you can load the saved mesh instead of re-probing.

You’re welcome to try, but don’t get mad when your fan blows up.
