Not sure if this goes here, but I'm building an arduino controlled rca switch / volume controller for an amp system using an ICE power 500ASP. My question is, can I use the -12v and +12v rails from the DC bus (or +12v and GND) on the ICEpower to get 5v for my arduino?
I was thinking on grabbing the Vcc (+12V) and PGND to get 12vdc and use a step down to 5v. Can this be a problem?
