Product Introduction
USBHUB, that is, a device that can expand one USB interface into multiple (usually 4) and use these interfaces at the same time. Hub is also commonly referred to as a hub, which uses a star topology to connect multiple USB devices. The USB HUB is expanded based on the 4 USB ports provided by the GL850G chip. GL850G has product features such as low power consumption, low temperature, and reduced number of pins, so it is favored by developers. USB HUB can be connected to computer desk lamp, computer fan, M3, U disk, voice recorder, digital camera, etc.

Precautions
This module is developed based on the USB2.0/1.1 specification. It is fully compatible with USB2.0. Using USB3.0 or higher may damage your device.
Please be cautious when using high-current mobile hard drives. Generally speaking, when the mobile hard disk is powered by USB, the working current is 0.5A-1A. Too much current requires high USB power supply. The USB Hub itself does not have an external power supply. It borrows the 5V power supply from the motherboard USB, so it may cause insufficient power supply and damage the mobile hard disk. And the transmission rate will decrease, which will affect normal use. It is recommended to plug the mobile hard disk directly into the motherboard.
