Zusammenfassung:	The utility model provides an SPI (Serial Peripheral Interface) communication board card and an SPI communication device. The SPI communication board card comprises a PCB (Printed Circuit Board) mainboard, the first clamping mechanism is arranged on the PCB mainboard, a first signal connecting piece is arranged at the first clamping mechanism, the first signal connecting piece is in signal communication with at least part of a circuit of the PCB mainboard, and the first clamping mechanism is used for being clamped with a second clamping mechanism of another SPI communication board card; and the first signal connecting piece is in signal connection with a second signal connecting piece arranged at the second clamping mechanism. Through the arrangement, the SPI communication board card can be in signal connection with another SPI communication board card through the first clamping mechanism and the second clamping mechanism, so that a signal propagation path is of a microstrip line transmission structure, a pro
