Because Raspberry Pi's are hard to get nowadays, I'm looking for an alternative single board computer.
I've seen several sites that list all kinds of alternatives, but those websites don't talk about the thing that is most important for me: software compatibility.
Ideally, I want to be able to pull an SD card out of a Raspberry Pi, put it in the alternative SBC and turn it on. But maybe that's too much to ask. It would already be very nice if I can add a few drivers to my Raspberry Pi OS installation and then be able move the SD card between the Raspberry Pi and the other SBC back and forth.
What single board computer is the most compatible with Raspberry Pi?
