6-way USB power distributor + power meter OLED display

Overview

Regarding hardware, as there are more and more small devices with various functions on the desktop, most of them are powered by USB interfaces. So I designed this small device to support a total of 6 USB interface outputs. Controlled by 4 torsion switches. It also supports monitoring the power of each USB output. 3 display modes. Only total power can be displayed. USB voltage, current, power of each channel, etc. It has relatively practical functions.
The main control is STC's 8G1K17A-SOP16. The source code can be used with other models of the 8G series. Already open source. You can join the group "967261086" and download all design materials for free. More small software and hardware works will be open sourced in succession. Everyone is welcome to discuss together.
