1The Y / CVBS, Pb, and Pr interfaces
The output interface of analog TV composite signal and chromatic
component signal, where Y / CVBS interface outputs composite signal
(CVBS) when the signal formats are PAL and NTSC, and the luminance
signal in chromatic signal (Y) in other formats.
2L, R joggle
Audio output interfaces, L and R represent the left and right
channels, respectively.
3HDMI joggle
Digital video signal output interface.
4.System peripherals interface
Easy for users to connect to the monitor, mouse, keyboard, U disk
and other external devices.
5.System power supply interface and switch
Connect and control the system power supply.
