What screen you use for your raspberry pi?
I prefer the mini size, like this 5-inch screen, which is light and suitable for carrying.
Not only can it be used with my Raspberry Pi, but it can also be used as a split screen to watch my stocks. Have you ever noticed that there are two micro USB interface on the screen. One is "Touch" interface, which is for touch function and power the screen. The other is "Power" interface. If you connect the "Power" interface , the screen can be powered on without touch function. I am planning the next small video to show how to use the two interface in the next video.
