Why is there a resistor and capacitor connected in parallel at both ends of the microphone (the part circled in red)? What is the role of these two components here? Can they be removed?
The circuit board I made is powered by the USB port of the computer. I feel that the voltage should be relatively stable. Is it necessary to add a voltage regulator circuit? I wanted to add a 7805 thr...
In a double-layer board circuit, if the top layer is covered with GND and the bottom layer is covered with VCC, how will this copper laying method affect the circuit and is there a simulation solution...
16. Object class manager: DCDC, here you can add the class of PWR, and add the power supply VCC, GND into the member list. Back to the PCB, the top layer to the bottom layer28. CrystalCrys...
