Who can send a 51 MCU experiment board?

I think it's better to make a piece by yourself, I also just learned, in April, I drew and welded a piece by myself, the board was printed with ordinary copper clad laminates, and then printed out after drawing, and then heat transfer, then corrosion, drilling, etc., in fact, it is very simple, just a single-chip microcomputer and then add some peripheral circuits, you can do it simple at the beginning, and you have a sense of accomplishment after doing it. At the same time, you can also learn a lot in the process of making boards, and also lay the foundation for making simple circuit boards in the future. If you want to do it, I have a schematic diagram and PCB, which can be passed to you, and we can also communicate during the process of making the board, come on!

I don't know if you sent it last time.,Just sent another one.,Work hard.,There's a sense of accomplishment after success.,Hehe.。

You can make one by yourself, the smallest system, and only a few dozen dollars, and you can do whatever you need such as peripheral expansion circuits, just do it, just an ordinary universal board!!

I also recommend DIY a minimum system to weld up a day or two, no matter how much the board function is bought, you will not be able to improve I can guarantee that you will encounter a lot of problems in the process of welding the board, such as the use of multimeters, virtual soldering or something, these are the experience is the cornerstone of making your own PCB in the future, but if you are just to cope with the graduation project or something, then I will not say more.

I can't afford to spend more than 100 yuan. Now it's going to cost hundreds of dollars for a casual meal. No matter how poor you are, you can't be poor in education.

And this kind of thing you invest more than a hundred dollars now. The future harvest is not measured by this hundred dollars.

How much time you can save by getting started with an experiment board.

This is still very necessary, the meaning of the development board is not the role of the development board itself, the main value and significance is the data and technical support, if you encounter problems, someone will give you guidance, you can communicate with your classmates.

When I was studying at that time, I followed the tutorial of Wu Jianying's development board, and there were many classmates who communicated and made things together, and in such an atmosphere, I would learn and progress quickly.

This is the biggest significance of the development board.

The role of this board is summarized as follows:It provides stable and reliable circuit boards and devices, reducing hardware design and debugging cycles.

Schematics are provided to provide a reference for future re-plates.

Provide a source**, provide a reference for learning and research, and reduce the energy of learning from scratch.

Provide technical support and reduce the time to solve problems encountered in learningFor new engineers, the development board is very useful, and various resources are also very helpful.

The experimental board is very cheap, only 40 78, and you must have an experimental board to learn a microcontroller, and there are at least 20 exercises.

It must be necessary, and the microcontroller must be experimented with by himself.
