And you? I believe Neil is right here, and this kind of shortcut can

There's UART, long rs/232 cable, and a GPS.

UART needs some kind of power supply, to present voltages on the
rs/232 cable.

GPS needs some kind of power supply to work.

They are different power supplies, and we should have way to tell them
apart.
