Raspberry Pi alternatives

I’ll be experimenting with a Pi5 at some point, but for now I have enough other SBCs that are unemployed. I’ve still got one Khadas SBC that’s free and I’m just about to free up a Pi3 from a now redundant role. The Pi3 will be going into a SkyCam. I’ve got all the parts and I’ve been waiting until now to free up a Pi because I couldn’t buy one when I needed one.
