GL850G-HHY22 USB expansion chip solution verification board

Overview

This project is used to verify the solution verification board design of the Lichuang Mall GL850G-HHY22 ( product number: C136617 ) USB chip.
This project is a sample project for the Solicitation Order for Lichuang EDA open source hardware platform solution verification module .

GL580G is a chip designed for four-port USB2.0hub.

There are two options: Micro usb port and type b. For a handicapped person like me, the type B interface is great.

Some m3 holes are designed to facilitate the design of the housing. You can also choose to use PCB as the shell, and the top plate and hub plate are connected with M3 studs, which has a strong sense of technology.

Just like the SL2.1A free verification board on Lichuang Mall , I personally feel it is very good. I have brought this with me several times when I bought devices. I made one for my own use and also gave it away to others. However, there is no hole for drilling screws in the large area of the board, so I really have no choice but to drill it myself. Think about how to design an independent power supply port. .

2020/5/8: Add the independent power supply port dc-005, refer to the official circuit of GL850 found online (it should be no problem), and change a little packaging. It looks like this, haha Lichuang’s 3D library is invincible
