USB to TTL module [USB-A and TYPE-C dual port input, with switch]

Overview

This project is modified based on the https://oshwhub.com/acha/ch340-opensource project of Mr. acha.
There was no problem in the self-test. The burning program and serial port usage were all normal, so I sent it out.
The silk screen I drew myself may be a bit small. I clearly left a space for the JIC number and it is useless. If you think it is not beautiful, you can modify the silk screen yourself.
There is no need to pay attention to it, it is a very simple little thing (remember to solder the self-locking switch last)
