Quick VBatt Question


#1

I’m hooking up a 3v backup battery to my Cobra for the RTC stuff and I was wondering if I would attach the battery’s (-) to any available ground pin. Or does that mess with the normal supply of power? I’m definitely not an electrical engineer, so I would rather not break anything (although I’m fairly certain that won’t happen).

Thanks for the help!

Any ground should work.
