Low-power consumption and high integration main board with a plurality of expansion interfaces

Abstract

The invention discloses a low-power consumption and high integration main board with a plurality of expansion interfaces. The low-power consumption and high integration main board with the plurality of expansion interfaces comprises a main board of a printed circuit, a central process unit (CPU) and a South Bridge chip, wherein the CPU and the South Bridge chip are integrated on the main board. A UNI-peripheral component interface express (PCIE) expansion interface, a high-definition multimedia interface (HDMI) / digital video interactive (DVI) / data processing (DP) control module, a PCIE control module, a hard disk control module, a universal serial bus (USB) control module, a recommend standard (RS) 232 / 422 / 485 control module, a voice frequency control module, a control signal module and a line print terminal (LPT) parallel interface control module are arranged on the main board. Pins are arranged in the UNI-PCIE expansion interface, wherein the pins correspond to the above-mentioned control modules. The pins are respectively connected with the above-mentioned modules through drive circuits. Compared with the prior art, the low-power consumption and high integration main board with the plurality of expansion interfaces achieves the unification of a plurality of external interfaces through the UNI-PCIE expansion interface, so that the structure of the main board becomes simple and attractive and manufacturing cost and energy consumption of the main board are reduced.

Description

Technical field: [0001] The invention relates to a motherboard, in particular to a motherboard with low power consumption, high integration and multiple expansion interfaces. Background technique: [0002] The motherboard is also called the motherboard, system board or motherboard. It is installed in the case and is one of the most basic and important components of the microcomputer. The motherboard is generally a rectangular circuit board, on which are installed the main circuit systems that make up the computer. Generally, there are BIOS chips, I / O control chips, keyboard and panel control switch interfaces, indicator light connectors, expansion slots, motherboards and cards. DC power supply connectors and other components. The mainboard adopts an open structure, and there are 6-15 expansion slots on the mainboard mostly, for the control card (adapter) plugging of the peripheral equipment of the PC. By replacing these plug-in cards, the corresponding subsystems of the mi...
