USB recepticle configuration and system therefor
A method may include selectively instantiating a bridge conductor component at a first printed circuit board (PCB) pad and a second PCB pad to provide a first universal serial bus (USB) receptacle configuration at an information handling system, the first configuration having a USB type-C receptacle at a first location at the PCB. The method may further include selectively instantiating the bridge conductor component at the first PCB pad and a third PCB pad to provide a second USB receptacle configuration at an information handling system, the second configuration having a USB type-A receptacle at the first location at the PCB. Instantiation of the bridge conductor component at the first and the second PCB pads is mutually exclusive to instantiation of the first bridge conductor component at the first and the third PCB pads.
