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. In fact, almost all the boards are "references" to the local gold CH340 of a certain treasure. I just copied the boards. Due to time constraints, we have not yet carried out proofing and welding tests, so there may be some problems with the board or schematic diagram. If anyone sees it, please help correct some mistakes and make some suggestions. Thank you!
