PC/104 standard describes module principle to build compact integrated systems in the form of a stack of boards mated to each other. The PC/104 standard has proved its high efficiency among developers of compact onboard computer systems. Many engineers chose РС/104 due to the advantages which include their low weight and dimensions of such devices (boards with dimensions 90×96 mm), mechanical reliability of both connectors and the entire structure in general.

Family of PC/104 standards describes data exchange between modules via 16 bit ISA parallel buses, PCI 32 bits and using PCI-Express, USB 2.0 and SATA serial interconnects and contains of 5 specifications. Despite the most compact size 90×96 mm, the standard family includes EPIC and EBX form-factors.
