Universal bottom plate design based on standard COMe

The invention relates to the technical field of computer hardware board cards, in particular to a standard COMe-based universal bottom board design, which comprises core boards of different processors and a universal bottom board comprising a plurality of interfaces, and the core boards and the universal bottom board are connected through a COMe interface; a CPU (Central Processing Unit) power supply system, a CPU clock system, a CPLD (Complex Programmable Logic Device) and a real-time clock module which can enable different processors to work normally are integrated on the core board; a PCIe expansion controller directly connected with a processor, a PCIe slot, a bottom plate power supply system, a bottom plate clock system, a DDR slot, a fan and peripheral chips are integrated on the universal bottom plate. The plurality of peripheral chips comprise a USB chip, an SATA chip, an audio chip, a network card chip and a video card chip. According to the invention, a standard COMe interface and a plurality of equ
