A stacked connector component includes a housing, connectors at a front opening of the housing and arranged in a stacked formation within one or more columns, and a for and exposed at the connectors. The pins include high-speed pins routed within the housing to a bottom side thereof and low-speed pins routed within the housing to a back side or a top side thereof. A circuit board includes pin pads connectable to the pins and disposed on a substrate. The pin pads include high-speed signal pin pads for the high-speed signal pins. The substrate includes contiguous high-speed areas in which the high-speed signal pin pads for the high-speed pins are located, between which no pin pads are located.
