[NUC] Front Panel Header for NUC
Most, but not all, NUC motherboards have a 9-pin or 11-pin (2.0 mm pitch) front panel header. This header is on the processor/fan side of the motherboard. You can connect a power switch to this header to remotely power on or reset an NUC board that is embedded (such as in a kiosk) in a position in which the chassis' power switch isn't easily accessible.
