What is the fastest and easiest way to build a small, fan-less embedded system?  

This article by Wolfgang Eisenbarth, Director of Marketing at Embedded Computer Technology, MSC Vertriebs GmbH, explains how computer-on-module (COM) solutions based on the Intel® Atom™ processor provide a full embedded computer on a standardized, prefabricated module. Paired with customized carrier boards that implement application-specific I/O, COM solutions can simplify and accelerate the design process.   

The new Qseven form factor is particularly appealing for fan-less applications because it was specifically designed for mobile and battery-operated applications. Qseven are square, measuring 70 mm x 70 mm. Unlike other COM designs, Qseven does not require a board-to-board connector. Instead, it leverages the Mobile PCI Express Module (MXM) technology developed for graphics cards in notebook computers. The MXM connector meets key design challenges for embedded developers. Because it was developed for notebook graphics applications, it is both rugged and able to support high-speed serial buses. 

While it is a relatively new standard, Qseven has already proven itself through widespread adoption. The Qseven ecosystem has grown to include a wide selection of carrier boards including off-the-shelf carrier boards for automation and point-of-sale (POS)/kiosk applications, as well as fan-less enclosures for industrial environments. 

This article explores the advantages of the Qseven architecture for fan-less designs and reviews the capabilities of example systems from MSC Vertriebs GmbH and show how these solutions can be applied to specific embedded applications.
