Introduction to power lines (three-phase), signal lines, IO lines, and special power lines. Common points: The wire itself is an impedance body. Why do wires get hot? Why is there a voltage drop? Why
Regarding the STM32 of LQFP144, can it be drawn as a 2-layer board?1. I refer to some development boards, most of which are 4-layer. Of course, the board size is relatively small and uses 0603 package
