Mini TTL adapter module

I don’t need to say much about what this is for and how to use it, everyone knows it. I can be considered a novice, and this is the first time I share a board I drew with others.  Because I am a weak junior high school student, I have never studied circuits specifically, and no one has guided me (I have no friends ... ) , so there may be some problems with the board or schematic diagram, and there may be problems with my understanding of the circuit. If anyone has a look, Please help correct some mistakes and make some suggestions, thank you!

Known issues:

1.     The usb cable is not long (seems there is no problem?)

Features:

1.     TYPE-C interface  

2.     No jumpers required, output 3.3v, compatible with 3.3v and 5v

3.     Small size

4.     " JLCJLCJLCJLC " is added very thoughtfully , so mom no longer has to worry about the customer number not being placed under the component.

 There are two versions; typec and micro version, remember to choose the appropriate version.

Update log:

BETA version: In the video, there is nothing to talk about

V1.0 : Added interface definition, smaller size

V1.1: Smaller, interface definition is gone

V2.0: Add micro port version, project completed

Today is my birthday. This is my 14th birthday gift.
