Hello, what about a Pine64 RockPro64, it has a PCIe slot where you can put a multiport ethernet card or other things depending on your project...
There's certainly a serial port usable as console on those too. Looks supported, according to : https://www.openbsd.org/arm64.html But you may want to wait for comments from someone with actual real world experience of openbsd on those, I don't own one. Regards -- Vincent Legoll
