I used a ROCK64 SBC with a USB3 hub and could never get it really stable. The USB3 hub connected the camera and a 500GB SSD boot drive. I tried a number of USB3 hubs but experienced issues with all of them. Rather than spend more money on looking for a combination of parts that worked, I went with the NUC. It uses more power, but it much faster and I've not had an issue for 6 months. I also don't use WiFi as it isn't full duplex, 5G attenuates more quickly than 2.4Ghz, and the use case just isn't suited to wireless. Much better to go with 1Gbe wired.

The drivers are another issue. QHY needs to find a good engineer to help with the cooling problem - it shouldn't be that hard to fix. The settings is also an issue, but is not unique to CCDs - I have to manually adjust the guide rates for every session for my CEM60 mount as they are not saved. Perhaps there were some unintended changes when the github repositories were reorganised. Over time, they'll get fixed I'm sure. I do have to say that in general, INDI is much more stable and the usability of EKOS get improving too.
