The price of STM32 has risen sharply recently. I want to buy some, but my pocket is tight. A brother in the group recommended Fake Bao, a company that makes wireless transmission.
They have a 433 wireless transmission module: the beginner package is less than ten yuan and comes with two STM32F103C8T6 bases and two 433 transmission modules.
Damn it, this guy is too conscientious! ! !
If you are interested, search it yourself!
Well, after I got the things back, I found that the 433 transmission thing is really easy to use and has good stability. There are almost no disadvantages except that long strings cannot be transmitted continuously.
The stuff is good, but the serial port module to plug into the computer is a bit expensive.
It's too expensive. If that doesn't work, let's just draw one ourselves. The KEY is the setting key. I won’t explain it in detail. You can read the official documentation yourself!
