A stable multiscreen solution is very important for many situations.

MPro driver boards are all using USB2.0 for best compatible, but for more than one screen, USB2.0 HUB is not enough for data transfer and power supply.

This solution is using USB3.0 HUB, its max speed is 5000Mbps, so it should be easy to connect to more than 8pcs screens.

USB3.0 HUB max output current is at least 10W, for our usage, screen only use approx 2W for each, so 4 screen at most 8W.

USBHub chip we can choose CH634F which cost is very low and we have tested it stable enough.

In June, we will make an open source demo board with at least three screens and also some WS2812B LEDs, hopefully this demo will help a lot for the production develop.
