This is for Bluetooth module, I'm not familiar with digital circuit. The power supply is simple , 5V ac -> full bridge -> CRCLC filter -> LM1117.
I know for digital it's better to pour ground for the lowest inductance. But from which point is good for reference ground?
another question I have is, for low inductance, does it have to calculated all the way to transformer, or just to the reference ground? or just the return path of signal?
Might be silly question, but thank you for helping
