System On Modules(SOM), or Computer On Modules (COM), are complete computers on a plug on module. Configuring the i/O on an individual carrier board tailors the functionality to the application, saves costs and shortens time-to-market
The ESMexpress standard has been developed for applications that require highly robust eletronics to ensure safe and reliable operation even in severe environment, eg. in railways and avionics, industrial automation and medical engineering or mobile applications in general.
The fanless cooling concept of ESMexpress is prepared for a power dissipation of up to 35W and supports both conduction and convection cooling. The CPU PCB is mounted into a frame and completely enclosed in an aluminim housing. The high pressure caused by the screw joints between the housing and the PCB supports the Thermal connection of the components. If an ESMexpress module needs additional cooling. At the same time it ensures optimum EMC protection for the electronic parts.
To be resistant against shock and vibration, the mdoule is fixed on the carrier card using eight screws and has a rugged board-to-board connector.
The Electival signals are distributed on tow 120-pin connectors and are only defined for the modern serial buses such as PCI Express, Gigabit Ethernet, USB, SATA, SDVO, LVDS, HD audio, several utility signals and as single 12V power supply. The pin assignment is fixed so as to guarantee the interchangability of ESMexpress modules.
Its open processor architecture makes ESMexpress ready for all Intel platforms such as Intel Atom or Intel Core. It is just as well suited for PowerPC CPUs, eg the MPC8548 from Freescal's PowerQUICC III family.
Because they are at the same time compact, rugged and powerful, SOM solutions are especially well suited for infotainment solutions, medical engineering, industrial automation, or railway applications. For example, MEN offers a standard display computer, the DC1 with a COM inside
