ETX concept and benefits 
 
" It doesn't fit" That's what you often hear when selecting CPU board for industrial,PC-based applications,The usual problems include wrong size, unusable connector locations and missing special functions. The Classic way of solving such problems by developing a completely new design requires a lot of time and is not flexible enough to react to ever-changing market demands.
ETX stands for Embedded Technology extended-the standard for industrial applications,this open standard fits the need of embedded applications perfectly. Because of this, it is supported by many board vendors who offer their own ETX designs.complete PC functionality is provided within the very compact 114mm x 100mm (4.5" x 4") dimensions of the ETX module. the use of a wide range of CPU classed allows for performance scale-ability. Using only four high-density connectors, The ETX is place on a customized baseboard that contains all of the custom, application-specific functions. 
On of the ETX feature is saves money,The end product and development costs are dramatically reduced.this holds true for product's entire life cycle. ETX provides a cost advantage from beginning.
ETX minimizes risk. basic changes during the design phase or in the middle of a product's lift cycle are no longer a problem. Simply plug in the next-generation EXT module and your are set. ETX makes upgrades easy.
 
ETX is flexible, Meeting all performance requirements, The ETX module supports a wide range of performance CPUs. The ETX standard is wide open.ETX puts you in the lead. The use of a customized based dramatically reduces necessary engineering by separating your design from that of the embedded PC technology. Use ETX in your design and stay focused on your core competency. ETX - easy design - huge time advantage.
