Qseven
Lua error in package.lua at line 80: module 'strict' not found. Qseven, a computer-on-module (COM) form factor, is a small, highly integrated computer module that can be used in a design application much like an integrated circuit component. It's smaller than other computer-on-module standards such as COM Express, ETX or XTX and is limited to very low power consuming CPUs. The maximum power consumption should be no more than 12 watt.
Since the release of Specification 1.20 (September 10, 2010) Qseven modules can be indifferently based on x86 or ARM architectures.

Interfaces
The Qseven specification defines a rich set of legacy-free interfaces. Older interfaces like PCI, ISA, RS-232 or EIDE are not supported.
- 4× PCI Express ×1 Lanes
- 2× SATA
- 8× USB 2.0
- 1× 1000BaseT Ethernet
- 1× SDIO 8-bit
- LVDS 2× 24-bit
- SDVO / HDMI / DisplayPort (shared)
- HDA (High Definition Audio)
- I²C Bus
- LPC (Low Pin Count Bus)
- CAN bus (Controller–area network)
- SPI (Serial Peripheral Interface Bus)
Size
- 70 mm × 70 mm;
- 70 mm × 40 mm.[1]
Connector
Qseven uses one 230 pin MXM2 SMT edge connector to connect all power and signal lanes to the carrier board. This connector is available from multiple vendors at different heights (5.5 mm and 7.8 mm).
Specification
The Qseven specification is hosted by the independent Qseven consortium. It's freely available at the consortiums website. The current revision 1.20 was released September 10, 2010.
Design Guide
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.
