The expansion board includes at least one group of connector pins and a processor. The at least one group of connector pins are coupled to a first connector that conforms to a first industrial specification to receive the transmission signal from the motherboard. Pin definitions of the at least one group of connector pins conform to pin definitions of a second industrial specification. The processor is coupled to the at least one group of connector pins to receive or send the transmission signal. Dimensions of the first connector are less than the dimensions of a second connector that conforms to the second industrial specification. ## Claims ### Claim 1 An expansion board adapted to be electrically connected in parallel to a motherboard, the expansion board comprising: at least one group of connector pins adapted to be coupled to a first connector that conforms to a first industrial specification to receive a transmission signal from the motherboard, wherein pin definitions of the at least one group of connector pins conform to pin definitions of a second industrial specification, and the transmission signal conforms to the second industrial specification; and a processor coupled to the at least one group of connector pins to receive or send the transmission signal, wherein dimensions of the first connector are less than dimensions of a second connector that conforms to the second industrial specification. ### Claim 2 (depends on 1) The expansion board as claimed in claim 1, wherein the first connector is a USB Type-C connector. ### Claim 3 (depends on 1) The expansion board as claimed in claim 1, wherein the second industrial specification is a PCIe transmission specification. ### Claim 4 (depends on 1) The expansion board as claimed in claim 1, wherein a direction of extension of the first connector and a plane where the expansion board lies are perpendicular to each other. ### Claim 5 (depends on 1) The expansion board as claimed in claim 1, wherein the second industrial specification supports a plurality of transmission channels, and pin definitions of the connector pins support at least one of the transmission channels, respectively. ### Claim 6 (depends on 1) The expansion board as claimed in claim 1, wherein the first connector is a male connector plug or a female connector jack. ### Claim 7 (depends on 1) The expansion board as claimed in claim 1, wherein the processor is a PCIe processor or a USB processor. ### Claim 8 A mainframe apparatus, comprising: a motherboard adapted to be electrically connected in parallel to an expansion board; at least one group of connector pins disposed on the motherboard and adapted to be coupled to a connector that conforms to a first industrial specification to receive a transmission signal from the expansion board, wherein pin definitions of the at least one group of connector pins conform to pin definitions of a second industrial specification, wherein the transmission signal conforms to the second industrial specification; and a processor coupled to the at least one group of connector pins to receive or send the transmission signal, wherein dimensions of the connector are less than dimensions of a second connector that conforms to the second industrial specification. ### Claim 9 (depends on 8) The mainframe apparatus as claimed in claim 8, wherein the connector is a USB Type-C connector. ### Claim 10 (depends on 8) The mainframe apparatus as claimed in claim 8, wherein the second industrial specification is a PCIe transmission specification. ### Claim 11 (depends on 8) The mainframe apparatus as claimed in claim 8, wherein a direction of extension of the connector and a plane where the motherboard lies are perpendicular to each other. ### Claim 12 (depends on 8) The mainframe apparatus as claimed in claim 8, wherein the second industrial specification supports a plurality of transmission channels, and pin definitions of the connector pins support at least one of the transmission channels, respectively. ### Claim 13 (depends on 8) The mainframe apparatus as claimed in claim 8, wherein the connector is a male connector plug or a female connector jack. ### Claim 14 (depends on 8) The mainframe apparatus as claimed in claim 8, wherein the processor is a PCIe processor or a USB processor.
