USB hub

Overview

If your computer, like mine, only has one port left after plugging in the mouse and keyboard, and connecting a USB drive is the limit, which is very inconvenient, then this 1-to-4 adapter is perfect for you.
With it, you don't need to program microcontrollers one chip at a time, saving you a lot of plugging and unplugging, which is extremely convenient.

There was a slight error in the 3D casing design; the bottom shell is 2mm shorter, resulting in only the cover being closed. If you use it, you can easily modify this slightly. It also comes with free printing!
