Godson 3ACPU, frequency of operation is 900MHz ~ 1GHz, CPU power consumption is less than 15W, and mainboard is integrated with provides each functional module of network, serial ports, USB, VGA, PS2 keyboard and mouse, audio frequency Peripheral Interface to be connected with mainboard with compatible 3UCPCI expansion card by 3UCPCIe expansion card;

Backboard adopts 5 groove multifunction designs, 1 system groove, and 4 3U board expansion slot, wherein slot 1 is standard TYPE I type CPCIe x16 expansion slot; Slot 2 is TYPE II type CPCIe x1 expansion slot; Slot 3 is mixed type expansion slot, compatible 3UCPCI expansion card and two kinds of boards of TYPE II type CPCIe x1, and slot 4 is standard 3U CPCI expansion slot, is convenient to user and expands as required corresponding functional interface;

Power module is used two redundancy CPCI power supplys, and power supply input range is 20-32V.

Excellent effect of the present invention is that this ruggedized computer adopts modular design, and each board is connected with base plate with CPCI connector by CPCIe, has greatly reduced the line between board, is convenient to maintenance and ensures.During maintenance, only need open case front panel wicket and change malfunctioning module and can deal with problems, without complicated line etc., greatly shorten the MTTR time, ensure the continuity of system.
