I want to create a PCB board that would have:
- input - 5V wall outlet USB charger or for example MeanWell Din power supply
- output - 3 usb ports that would be used by RPI-like devices. (5V 2A max each).
Question - since all devices would share same power line and I can expect noise from the consumers - could you please point at extra circuit items that I should use ?
I would imagine that it should contain capacitors from 5V to ground near each output and probably optional input capacitor (not sure if needed with quality power supply's).
And I would also assume that RPI-like devices have already some input filtering in place, so probably it would be overkill.
Also, there would be no data lines included, just the power lines.
