I can't answer your question directly but here is my experience.
I run indi on a PI 3B+
I run kodi (media player) on a Tinker board. It has run for months 24/7 without any issues, no reboots..
The Tinker Board is great.
However I use Raspbian on the PI and Tinker OS on the Tinker Board.
I have not yet tried indi on the Tinker but may do one day.
I guess you my need to go the source build route to get the latest versions of indi etc. Also true fro Raspbian on PI.
I am consitering upgrading my indi PI to a Gigabyte Brix so I can run the intel builds of indi etc.
It does use more power though.
If it fails to work, you can make a media player out of it.
2 gb RAM! and internal FASTER drive - and still a SD slot for moving files and taking them with you.
I'd like the faster writes of imaging files to the 16gb!
FYI Stellarmate won’t run on anything but rpi.... just in case you think it will....
