Overview

The USB-hub module based on the fe2.1 ([product number C39693](https://item.szlcsc.com/40676.html)) chip, fe2.1 uses the mtt protocol, which is faster and more stable than the stt of fe1.1. The module has overcurrent protection and a total of 4 USB interfaces have been expanded, which can be expanded to 7 at most.
The module has two versions:
1. USB power supply version, powered by the USB-typec interface, U disk, keyboard and mouse and other low-power appliances can run stably, if you want to play with mobile hard disk, it is best to use the DC power supply version.
2. DC5V power supply version, with a DC5V power supply interface, can drive high-power devices such as mobile hard disks.
