Abstract
A PCB having a card slot receiving a card provided with signal input/output pins and a circuit element to provide extended capability is inserted, and having data transmission pins, a power pin and a ground pin in correspondence to the signal input/output pins, comprises an electronic device internally provided for impedance matching with the card, and having a first end connected to one of the data transmission pins and a second end connected to one of the power pin and the ground pin. With this configuration, a card slot internally comprises an electronic device for impedance matching, so that a space of the PCB can be efficiently utilized.
