USB3.0 one-to-four hub based on VL812
Use USB3.0 square mouth male data cable to connect to the computer, expand the USB interface.
There is a power indicator and each interface indicator.
The firmware can be downloaded to the SPI, no need to power on every time To download the firmware manually.
Externally expand the DC-JACK power interface, which can input 5V power supply.
Use the C69417 of VL812 as the main control chip, integrate 5V-3.3V and 5V-1.2V circuits, which can reduce peripherals Circuit.
The common mode inductor and TVS tube are added to the USB3.0 interface, which are used for EMI filtering and anti-static.
The 5V input has a fuse to prevent the circuit from being burned.
The PCB is designed with six regular hexagons Interface (1 power input, 1 USB input, 4 USB ports).
