Basically a small touch display with optional camera and motion sensor.

I wonder if this could be used to DIY a Linux phone with a small well supported ARM SBC and a 4G USB dongle on a belt clip or so? Wireless display transfer seems to be supported or could be probably done with a USB-C cable as well? 🤔 Edit: Display probably needs a cable, but you could use the build in wifi + bt via that cable, so the SBC wouldn’t need their own?
