I planned to use a 4.3" car reversing camera monitor for my screen. I'm wondering if others have tried this. My problem is that when I power up the monitor from a 12v power source I don't get any result. I was expecting to at least get a blank lit screen. Is there some input needed from the camera (...

I'm intending to use a bluetooth keyboard which necessitates a USB dongle.

Most dongle suppliers list only windows operating systems as acceptable.

Will these dongles actually work with the linux debian supplied on the SD card or do I need another type of dongle
