'Uninteruptible' Power Supply
Posted: Mon Jul 15, 2019 11:27 pm
I've set up my pi to be able to directly plug to 120vac by using a step down converter to get a constant 5v supply. I have a 3.5V rechargeable battery hooked up in parallel and my question is:
-If the pi happens to lose the 120vac supply and therefore the 5vdc, would 3.5V rechargeable battery be enough to let the pi safely save its working memory and shut down?
I'm pretty new to raspberry pi; would a sudden power supply drop from 5v to 3.5v affect it? Or is there some kind of built in safety?
Thanks!
