Please help me with some advice. How to connect the four pins of the oscillator? Does it output the frequency directly or does it require some peripheral circuit? I recently wanted to use an active os...
[color=#252525]The question stipulates that the voltage regulator diode is not allowed, so how should this circuit be modified to only use capacitors, resistors, inductors and other components? I am a...
In order to cope with the shortage and price increase of chips, in addition to trying every possible way to find domestic alternatives, there are also some people who use different channels to look fo...
