[Successful test] USB-HUB docking station based on SL2.1A

Overview

1 USB-A input, 4 USB-A outputs (don’t ask why you don’t use Micro or Type-C, you just don’t want to use them)
Each output has a 6V2A resettable fuse (not included in the input/IC part)
The input/output is equipped with capacitor filtering (there are a lot of capacitors, which are useless if not used)
R2 determines internal or external crystal oscillator

log

I haven’t written the previous log, so I’ll ignore it for now. I received the PCB today and completed the welding. After powering on, I can install the driver. I will conduct a speed test when I have time. QQ screenshot 20200508140655.png QQ picture 20200508140016.jpg
