How to work correctly with GND and PWRGND?
There is a circuit of me with a couple of bucket converters. The bucket converters are either standalone or getting a PWM signal from a processor and give a feedback to the processor.
As far as I know, a star topology is quite useful to avoid EMI problems. How could I do this correctly in KiCad? Is it a need to separate the ground signals with an transformer or a optocoupler?
