Problem Description

Most of the HUBs you can buy usually come out of the womb and the umbilical cord is not cut. They come with a USB-A or Type-C cable, which greatly affects the performance. You can only leave it alone. The computer interface is very close. I want to make it like this: "As long as there is a long enough cable, then my HUB can be placed where I want."

Implement Function

1.Using Type-C input

2.1 Type-C female connector to 4 USB-A female connectors

3.Overcurrent and short circuit protection (programmable current limit setting)

4.Power indicator

5.Showing the beauty of color screen printing

Shell Design

It adopts a three-layer structure + 3D printing outsourcing form to reflect the beauty of color silk screen printing as much as possible. The upper and lower panels are made of transparent panels, with a color screen printing PCB in the middle. Finally, it is covered by a 3D printed shell. From the EDA professional The main structural parts, input and output structures are exported (there is no full guide when verifying the shell, which is too much for a small computer). The main drawing is the upper and lower panels and the shell. For direct use, you can directly use "shell.STL". Assembly.SLDASM is their assembly. You can see the final effect and download the compressed package if you want to modify it.

Panel

You can add patterns and various colors to the panel by yourself. Remember to set the transparency so that the colorful silk screen inside will not be completely covered and lose its bright appearance and be buried in the shell and panel.

Physical Display

Miscellaneous Chat

• Just change the colorsilk screen photos according to your preference.
• There is a good saying, USB 2.0 can generally run as long as it is connected, but I am used to doing the package processing.
• Because it is a colorsilk screen, when it is put into the case, both the front and back sides must be exposed, so that you can view both the front and the back.
• In order to accommodate four USB-A and place a colorsilk screen that is not too compressed, the board is designed to be very open. All resistors and capacitors are packaged in 0805 to facilitate soldering (Type-C and chips are slightly more difficult to solder)
• I forgot to add the indicator light when making the board. There is no indicator light in all physical displays (the indicator light has been added during the project)
