Computer mainboard based on Feiteng X100 nest plate

The utility model relates to the technical field of computer interface expansion, in particular to a computer mainboard based on a Feiteng X100 nest plate, which is provided with a domestic CPU (central processing unit), the Feiteng X100 nest plate and a CPLD (complex programmable logic device) chip. The Feiteng x100 chip set is connected with the domestic CPU through a PCIE (Peripheral Component Interconnect Express); the CPLD chip is connected with a QSPI interface, a GPIO interface, a UART1 interface and a UART0 interface on the domestic CPU. According to the utility model, the interface expansion is carried out based on the Feiteng X100 chip, and due to the abundant IO widening function, the requirements of clock differential signal driving, serial ports, display interfaces, USB (Universal Serial Bus) interfaces, PCIe expansion, SATA (Serial Advanced Technology Attachment) interfaces, time sequence control and the like can be met on a single chip, and the real-time temperature monitoring and intelligent f
