4+1 docking station

Overview

The 4 plus 1 USB 2.0 docking station is made with FE1.1S chip, and the price of the chip is less than 4 yuan.

In actual testing, it can reach 2.0 full speed, no delay, no lag, and low heat generation.
The attachment is a 4-port one, and the one shared is a 4+1 one, which was successfully verified. I forgot to take a photo and
modified the position of the LED light to display the working status of the chip and the working status of the port.
Thanks to blogger @JJ—KING for the schematic diagram
