A Brief History

Qseven is an embedded computing standard that defines a small form factor computer module. The standard was first introduced by the Qseven Consortium, a group of companies in the embedded computing industry collaborating to develop and promote this standard. The Qseven Consortium was formed in 2008, and the first version of the Qseven specification, version 1.0, was released in 2009. The following year, Specification 1.20 was introduced, allowing Qseven modules to be based on both x86 and ARM architectures. Since 2013, the Qseven specification is hosted by the Standardization Group for Embedded Technologies (SGET).

The goal of the Qseven standard is to provide a compact, standardized, and versatile platform for embedded systems. Qseven modules typically incorporate key components such as processors, memory, and various interfaces on a small-sized module. This modular approach allows for easier integration into different embedded systems, reducing development time and effort.

The Qseven standard has undergone revisions and updates over the years to keep up with technological advancements and to address emerging needs in the embedded computing industry. It has gained popularity in applications that require small, power-efficient, and scalable computing solutions, such as industrial automation, medical devices, and other embedded systems.

Did you know that the name Qseven is derived from ‘quadratic’, which is represented by the Q and ‘seven’ referring to the 7 x 7cm size of the module.
