I do run OpenPlotter on a Raspberry 3B model while the Intel NUC provides more then needed CPU/memory for OpenCPN.
The Intel NUC runs on 12V, I simply wired it to the 12V circuit. There is a small inconvenience however.
When docked in the marina and the battery charger activated, the NUC detects a voltage which is to high (>14v) and refuses to boot. I simply turn off the battery charger for 5 seconds and let my fridge/lamps/electronics draw some power from the battery, then the NUC boots fine and is perfectly stable (for days), even with battery charger back on.
The same issue reproduces itself when under way at sea on engine power. I simply power on a lot of lamps just to get a large draw on the batteries to get past the Intel NUC error prior to booting. This is not really an issue because the Intel NUC runs stable for days and nights. I prefer a device mounted high and dry over a laptop which can fall and break, especially because I use it for radar as well.
I do plan to test with the USB 3.0 monitor straight on my Raspberry so that I can eliminate the Intel NUC.
Possibly the USB 3.0 monitor + Raspberry won't work without an optional USB 3.0 Y cable + powered USB 3.0 HUB (don't mind the Raspberry 3B only supports USB 2.0 high speed, this is not an issue, it should work).
My hope is to get the monitor working withouth the optional cables. According to the official Raspberry site 1.2A (6W) is the max. total power draw for USB peripherals. The monitor uses 5W according to some sources, "<7W" according to other sources.
The driver issue from the past has been sorted out as well, it works on Linux Ubuntu/Mint/Fedora and also on Raspbian (providing sufficient power is available).
As soon as I have a good result, I'll post my findings here.
