Specification

The name comes from the word "quadratic" due to the square shape of the original module, 70mm on a side. It was first proposed in 2008 by Congatec. Other companies based in Europe such as Kontron adopted the standard, but after a few years it had not yet been popular in the USA. The Qseven specification is hosted by the Standardization Group for Embedded Technologies (SGET), which took over from the original Qseven consortium in 2013.. The revision 2.0 was released September 9, 2012, and 2.1 on February 25, 2016. The Qseven design guide provides information for designing a custom system carrier board for Qseven modules. It includes reference schematics for the external circuitry required to implement various peripheral functions. It also explains how to extend the supported buses and how to add additional peripherals and expansion slots to a Qseven-based system. It's available from the Qseven consortium webpage. Since the release of Specification 1.20 (September 10, 2010) Qseven modules can be based on
