the port board 2 is provided with an output port 21, the side edge of the port board 2 is provided with a plurality of conductive contact pieces 22 corresponding to the output slots 13, the side edge of the port board 2 is inserted into the output slots 13 so that the conductive contact pieces 22 are electrically connected with the output slots 13, when the port board 2 is inserted into the output slots 13, the position relation between the port board 2 and the expanded chip carrier board 1 is changed into a three-dimensional structure from the traditional situation that the port board 2 is positioned on the same two-dimensional plane, the port board 2 is perpendicular to the expanded chip carrier board 1, so that the long edge of the rectangular output port 21 is perpendicular to the expanded chip carrier board 1, and the expanded chip carrier board 1 can be smaller depending on the distribution structure;

meanwhile, the plurality of port boards 2 are divided into a straight-out board and a conversion board according to the types of the expansion ports, the output port 21 on the straight-out board is consistent with the output end type of the serial port expansion chip 11, namely, the serial port expansion chip is a UART port, and the straight-out board can be reserved when the UART is directly used for equipment connection if needed;
