Hi All,
I have always been told that whenever using any type of microcontroller it's a good idea to use at least a 4 layer board. 1. Signal, 2. GND, 3. PWR, 4. Signal. I know that this is trying to battle high frequency noise, crosstalk, EMI, and issues associated with that.
Does anyone have or know of some solid pros and cons of a 4 layer PCB compared to a 2 layer PCB? Or are the ones I mention above a pretty good summary of the two different styles of boards?
