Qseven - the Mobile COM Definition
The Qseven specification is hosted by the Standardization Group for Embedded Technologies - SGET. Find the latest Qseven specification here: https://www.sget.org/standards/qseven.html
Targeting next generation ultra mobile embedded processors built using latest mobile chip technologies, the Qseven® format complements the low power and small size of these processors. By exploiting the small form factor of the industry’s latest processors, the Qseven® format offers high performance computing power, delivered in a module measuring only 70 x 70 mm² or 40x70 mm².
Qseven® allows for the use of non x86 processor architectures. It also supports the low power mobile ARM processor architecture. Customers have the freedom to use all kinds of Qseven® modules without the need to change the carrier board.
Qseven® is an optimized standard targeting towards low power and mobile / ultra-mobile applications.
Qseven® is defined for a maximum power consumption of 12 Watts. It is designed to be operated by single 5 Volt DC power and provides all additional signals for battery management. This simple power requirement allows for small mobile solutions powered by compact two cell batteries.
Qseven® does not require an expensive board-to-board connector. Instead, it utilizes a very affordable MXM2 card slot with 230 pins in a 0.5 mm configuration.
Qseven® is a legacy free standard focused on high speed serial interfaces such as PCI Express® and Serial ATA. Qseven® omits support for legacy interfaces like EIDE and PCI, in order to provide ideal support for today‘s, as well as future, mobile CPUs and chipsets.
The module‘s dimensions are a mere 70 x 70 mm². This means it can be easily integrated into size constricted systems. The even smaller μQseven definition is 40x70mm² only but is limited to support ultra-low power CPUs only.
When comparing to COM Express® Basic & Compact and SMARC, Qseven® enables slimmer mechanical housings.
The Qseven® Specification is hosted by the SGeT standardization group founded in 2012. congatec is founding member, board member and Qseven® development team member of the SGeT.
