I'm a developer by trade, but I am not the most knowledgeable when it comes to the hardware side, so please forgive me if I am not detailed enough.
I would like to find an all-in-one (i.e., screen and OS in one unit) device to run a Linux distro. on (preferably pre-installed). It will be used for digital, in-store advertising (for an example, see here), so for security's sake, minimal functionality is important (details below). What I have found on the market does not allow for any customization (i.e., access to the OS).
Attributes:
- Screen (preferably not touch) and OS in one unit
- 10" screen, give or take; some flexibility can be afforded here
- WiFi
- At least one USB port
- Does not need to be very powerful. A Raspberry Pi 3 has tested to be sufficient
- Sound output preferred, but optional
Cannot have:
- Camera, microphone, or any other similar device capable of gathering information from the immediate environment
- Affixed keyboard
