Qseven is a Computer-on-Module (COM) standard for small sized and highly integrated systems adopted by SGET.
The Qseven concept is an off-the-shelf, multi-vendor, Computer-on-Module that integrates all the core components of a common PC and is mounted onto an application specific carrier board. Qseven modules have a standardized form factor of 70 mm x 70 mm or 40 mm x 70 mm and have specified pinouts based on the high-speed MXM connector, regardless of the vendor. The Qseven module provides the functional requirements for an embedded application, which include, but are not limited to, graphics, audio, mass storage, network and multiple USB ports. A single ruggedized 230 pin MXM connector provides the carrier board interface to carry all the I/O signals to and from the Qseven module. This MXM connector is a well-known and proven high-speed signal interface connector that is commonly used for -PCI Express graphics cards in notebooks.
The Qseven footprint is smaller than that of COM Express, ETX or XTX, responding to system designers' needs for minimal space. Qseven's power consumption envelope is below a 12 watts target, whereas SMARC's target is below 6 watts and COM Express can be well above 20 watts. Therefore, Qseven designs provide mid-range power values between those of SMARC and COM Express.
The Qseven pincount is 230 compared to 314 and 440 for SMARC and COM Express (Type 2), respectively. Thus, it is optimized for designs with lower board-to-board pin requirements.
