Anyone here have a favorite "clever" way of controlling uart and power to an arbitrary SBC, for lab purposes?

) @trini I see you still haven't gotten an answer. I myself am not sure what you're asking; "lab power" usually just means a bench power supply, and although I've interfaced to uarts, I don't know what is a "clever" way.
If I'm the only one drawing a blank, ok, that's just me, but otherwise it conceivably could help to explain your question more? Maybe?
@dougmerritt Ah, good point. So I should perhaps have said "remote lab". A for-example problem is that if you take a Pi 4 the power connector is micro-USB but needs to be 5V/3A which is tricky to get reliably. A very unclever way to do all of this is with a remote controlled PSU like https://dlidirect.com/products/new-pro-switch and a hopefully good enough power adapter for the Pi itself. However, scaling that up to 8 boards takes a lot of physical space. I know some people have done things with relay controllers.
