Will core be working properly when 3000uF capacitor on power line?

My current project has big 3000uF capacitor on 5V voltage in line
I use it to reduce power drops when powerful servo attached to same power line stucks

Without capacitor Arduino Nano board resets itself
With capacitor Arduino Nano preforms perfectly well

Will spark code work well in same environment?

My cores arrive only in ~40 days, so I can’t test myself

@ryotsuke Hard to say without testing, but if the purpose of the capacitor is to maintain a consistent 5V, then it should work fine

Yes, that should not be a problem. But ideally, use a separate power source for powering servo motors since they introduce too much noise on the power line.
