Pine is a company that goes like “there is cool hardware in the world lets throw them to the wall and see if it sticks”. Lots of interesting hardware with stuff like PCI-E adapters on SBCs but you’ll have a rougher experience than what you’d have with Raspberry Pi’s or just plain amd64 hardware.
Nothing wrong with that and I actually favor RockPros over pis but don’t expect to have a library of software as big as the one for RPis.
