[i=s]This post was last edited by cruelfox on 2017-2-18 19:47[/i] Last year, I wanted to build a 144-pin STM32F7+SDRAM board for audio processing algorithm development. Although I got a powerful F746G
Why is it that when I use my RC voltage reduction solution in actual mass production, some of the product relays do not work, resulting in the AC 220V motor not being able to shift to high or low gear
Semiconductors are generally made of two materials, germanium and silicon. Since the temperature of the environment we live in is not absolute zero, there will be intrinsic excitation (electrons break
