I use a 52 MCU and L298 to drive a DC motor. My L298 is not connected to any devices. I found that when L298 uses a common power supply, the MCU often freezes or runs away. After the power supply is s...
When submitting the board, I found that the number of layers of the board is an even number. In fact, I am a little curious. Why are three-layer boards rarely seen in PCB design? It can even be said t...
