stm32f103 core board based on m.2

Overview

So if you want the length of 2230, you can polish off the back part yourself. The power supply of the interface follows the standard m.2 keyb pins, of course. I don’t want any idiot to plug this board into the m.2 of my computer. Also, why is it a four-layer board? Isn’t it because Jialichuang offers 4-layer boards for free? I deliberately painted it as a four-layer board to try. Of course, it is still recommended to use double-layer boards.
After all, the circuit is simple. It is also very convenient to change the double-layer board in this project, because there are basically no traces on the inner layer, so just move the two traces on the inner layer back to the top layer.

By the way, for programming, the four-layer board project supports bare board programming. The four pads on the back of the board are the programming pins.

[Help] I changed the chip, but it still won't burn, what's the problem? Urgent!!!
I made a circuit board with f123, using chips from 2 years ago, and successfully burned and debugged. I accidentally burned the chip, and replaced it with a new one (just bought), and then it prompted

Bendable flower-shaped solar cells
When I think of batteries, my first thought is that they are straight and only about 5cm-10cm long. But at a solar energy exhibition in Tokyo, Japan, a solar cell model made into the shape of flowers
[Help] Why does the program not run when the board is powered on after being separated from the emulator?
The task assigned by my boss is finally almost done, but now there is another problem. The program can run without the emulator. But the day before yesterday, after I connected the serial port of the
