I accidentally discovered that the operating voltage range of a microcontroller is 5.5V-28V. This made me very curious in an era when 3.3V is the mainstream?I know that most automotive-grade MCUs are
As shown in the picture, I use it on a motorcycle. The IO is connected to a 3.3V microcontroller. It works fine when it is just installed, but after two days of use, it is accidentally turned on. The
I won’t say who it is specifically, but I can only say that it is one of the best suppliers in the domestic industry.We used to work with suppliers in Taiwan, which are among the best in the global in
Some time ago, in order to make a small device, I first selected STC89C52 as the processing core. Later, as the functions continued to be enriched, the program became larger and larger, and the small
I got this board a long time ago. I had never come into contact with RISC-V before. I have always heard that RISC-V is the closest open source alternative to ARM. I have always wanted to get in touch
