I have a 5v 10A power supply that I am using to power my project. The project consists of a raspberry pi and 3 servos that are controlled by the pi through a PWM driver. The 3 servos and the Pi are powered from the same power supply.
The problem is that when I move all 3 servos I see the low voltage indicator pop up on the Pi. I don't have an oscilloscope to test how much current the servos are using but peak current is 600mA so the power supply should be sufficient to power everything.
Is there a way to split the incoming +5v into 2 isolated +5v rails that share a common ground?
That way I can use one rail to power the Pi and the other rail for the servos without the voltage drops triggered by the servos affecting the Pi.
I need to have a single power input that goes into the housing so I can't use two power supplies to power the Pi and servos separately.
Edit: Here is a an image of the circuit. I've marked out the important parts to make it clearer:
