Question: Power from 5v? #38

Open ammmze opened 1 year ago

ammmze commented 1 year ago

I've got a printer where I'm running a 5v PSU for my current pi and some lights. The 5v PSU is always on and the pi controls a relay to turn the 24v PSU on/off. I am looking to potentially replace my existing pi with the MKS Pi, but as far as I can tell, it cannot be powered by 5v? The power input looks like it supports 12-24v.
