I was hoping I could buy a cheap tablet and keep it plugged in, so I bought the DragonTouch Notepad K10 10 inch which runs Android (https://www.amazon.com/Dragon-Touch-Storage-Quad-Core-Processor/dp/B07WLNZB78).
This worked well for a couple days (running like 50-60 hours) and then the tablet crashed. The tablet feels fairly warm while plugged in after a while so I suspect that it overheated. But it’s also cheap and refurbished so it may be a lemon.
Any suggestions for an alternative? I would like screen size to be at least 9.7 inches, but not too big that it’s difficult to mount to the wall. I would also like to keep cost to under $300. The CPU/RAM requirement is pretty much insignificant because the animation is so simple. The K10 tablet handled that fine. And I’m open to an option other than a tablet.
