Done that. Sector-by-sector back-up.
My guess is that you should resize the contents of the 32 GB MicroSD

Yes. This is how I would like to do this. Is it possible to do this while
the SBC is online? It resized the image online on first install from about
a 4Gb partition to a 32Gb partition. It was a pre-built image. Download,
write image to SD card, insert card in SBC, turn on and follow instructions.

I followed the Armbian link as it's the only up-to-date and supported
distro on offer.

Yep. I can SSH into it. I have a USB to 3v3 TTL RS232 board and can
connect to the serial debug port and also the ability to connect USB
keyboard and mouse and a HDMI monitor.

Followed instructions when the USB to 3v3 TTL RS232 board arrived as it
appears this is how to start and complete the initial start-up otherwise
the SBC appears to be dead.If it's in the instructions then I missed that
and nearly threw the SBC in the trash. Glad I didn't as it appears to be
quite reliable.

Actually, here is a lot more technical information about this SBC: Output
from 'sudo armbianmonitor -u' = http://ix.io/3A1l

I'm guessing if the file system can be expanded online then it should be

Any help that I'll be able to understand would be very much welcome.
