Let's first briefly introduce the operating principle of LCD. As shown in the LCD schematic diagram below, each dot in it is a pixel. Imagine there is an electron gun that emits light of various color
A schematic diagram found on the Internet. Now replace the L in the diagram with a passive crystal oscillator, as shown belowCan this achieve oscillation? Does oscillation require R1 to be much larger
It's not fun if you can't debug. I can't afford an expansion dock, so I soldered two DF12 (4.0) male connectors to an emulator and tried it. I searched many stores and finally found one that was reaso
For a 5V output LDO, such as TPS73501, if the input is 5V, will the output be 5V? If the input is less than 5V, such as 4.7V, will the output still be a stable 5V? I know this design is not acceptable
