Runcam micro Swift 2 voltage wiring

If I want voltage OSD from my runcam micro Swift 2, can I simply wire the voltage OSD wire from my micro Swift 2 to my lipo positive wire, while running the micro swift 2 off a filtered 5V from my FC?

My lipo is a 3S.

Will this cause a voltage difference in the GNDS and dry something or cause unknown behavior?

Sounds like you got it right. At least Im not having problems using the wires like that, exept for a cold solder I managed to make that caused the OSD to show the voltage wrong :sweat_smile:
