COM Express™ was defined by the PICMG® (PCI Industrial Computer Manufacturers Group) as an open specification without hidden hooks. New module formats have been adopted recently.
Qseven™ Modules
Qseven has in recent years become the most widely adopted new standard for small form factor modules, specifically targeted towards applications that demand low power consumption.
ETX ® Modules
ETX ® will continue to be the platform of choice for systems requiring CPUs with low power dissipation and support for legacy interfaces such as the ISA bus, PS/2, LPT or COM1/COM2.
nanoRISC ® Modules
The nanoRISC ® module standard has been created for applications requiring a small form factor and lowest power consumption. These modules can be used as a processing supercomponent, while users only need to add application-specific periphery.
EXM32 ™ Modules
EXM32 modules, based on popular RISC CPUs like RMI Au1250 or the Freescale i.MX35, offer an ideal COM concept for rugged conditions, extended temperature ranges and lowest power consumptions.
