Little turtle expansion dock

Description of work

Hub is a commonly used consumer electronic product. When studying and working, we often find that the USB port on the computer is not enough. As an electronic person, why not make a soulful docking station that suits your own style...

Precautions

1. PCB routing

Since the four TypeA female sockets are in a "cross" layout, it is not easy to route the differential pairs. Pay special attention to the equal lengths. Spend more time to route the wires well.

2.Hardware welding

During the soldering process, it was found that the TypeC male socket and HUB chip are prone to weak soldering! ! ! I also found that after soldering at the beginning, the computer could not recognize it and could not be used. After checking for a long time, I found that one of the pins of the HUB chip was soldered, so I had to be very careful. After soldering, I must use a multimeter to test each pin. Are the pins soldered correctly?

3.Model shell

In the early stages of design, I made the PCB of the docking station into a shape similar to a turtle. In order to make it more realistic, it was necessary to add a 3D shell, so that the overall product would be more like a small turtle.

But, I drew a few small turtle shells myself, but they looked a bit awkward, and I couldn’t find a suitable one online. So, I put the shells away for now and will add them to the attachments when I find a suitable one (Okay! ).
