My STlink+232

Overview

Design a STlink V2.0 && CH340+232

The two circuits share power distribution and ground. The upper circuit is CH340+232. CH340 and 232 can be used separately or together;

The bottom lane is STlink, which leads to the download port that I often see in my work. In order to beautify my desktop, there are not so many messy lines;

The link size is 54*36mm, which is not as small as the design;

The download port of the company's circuit board is added to facilitate downloading, debugging and use by yourself, and you can save those obstructive adapter boards and cables;

I prototyped a 3D shell on the 3D Monkey, which seems to be quite easy to use;

Download the BIN file to the microcontroller through the downloader and flash it into STlink or DAP;

Then use STM32CubeProgrammer to update the latest firmware
