7-Inch-1024x600 Capacitive Touch Screen ( Extend Two USB HOST Port) With 720P Camera

Description

This is our brand new product, it is a fantastic 7 inch HDMI monitor with capacitive touch screen and 720P Camera module and it's driver free.
It's been tested on Raspberry Pi, beagle bone black, windows 10 and Mac book pro.
And it works well on those platform and it really plug and play, all you need to do is to adjust the resolution(on RaspberryPi).

It supports 1024x600 resolution and you may find that the pictures are more bright when you are using this display.
The capacitive touch function give the user full control over any device.
It's driver free for your device due to built-in EDID device information, it is very easy to let the equipment correctly identified the touch screen.
And the Capacitive USB touch screen can support functions of the right mouse button and drag and drop,
and also support multipoint touch, maximum 10 points.(only test in windows 10)

For use with a Raspberry Pi we suggest editing config.txt to set the HDMI to the native 1024x600 in case it doesn't detect the resolution properly.
The easiest way to edit the config.txt is to put the Pi TF card into an every day computer and edit config.txt with any text editor and save.

And most valuable things is it has been extended with two USB HOST ports.
So that you can hookup more USB devices to your screen, for example, the USB dongle or the USB mouse or keyboard.

There is 720P Camera module onboard,You can use this camera to take photos, even live.
It is very high clarity, but low power consumption and compatible with UVC standard, and Plug-and-play features.
