In personal chat, I would like to thank JLC for the colorsilk screen printing. It is very beautiful and the colors are very bright. I hope there can be such activities again. Secondly, it is also a preparation for my own study. I have learned a lot. Thank you very much.

If you are not good at welding, you should use solder wire with reasonable price and strong fluidity. This will get twice the result with half the effort when welding the lqfp chip. If you are not proficient, you can practice more and you will soon be able to master the skills and benefit from it. You can even slightly change the micro usb port. Replace with the same device with larger pins to avoid failure that will damage your confidence.

The circuit has been tested and can be used normally. The chip uses stc12c5a60s2. The instruction code is fully compatible with traditional 8051, but the speed is 8-12 times faster. We can see that port com4 is connected normally and the program can be burned normally.

The circuit diagram is as follows:
