2.1 Introduction

CQ7-A42 is a carrier board for Qseven

with release 2.0 of the specifications, including those introduced with the Errata to rel. 2.0 published by SGET consortium.

Qseven

is a form factor designed to minimize space consumption, since it integrates in only 70x70mm of space all core components of a common PC

architecture (CPU, RAM, Graphic, audio, etc.). All the functionalities are made available through a standardized card edge connector, from which all signals can be

taken and carried to the appropriate external connector in the carrier board and/or to other internal component, to implement more functionalities other than

included in the standard Qseven

bus interface.

The connection to the Qseven

board is implemented through a standardized MXM connector, which is a proven high speed signal interface connector.

The board has been specifically designed for taking advantage of all possible features that can be offered by x86 and/or ARM architectures on Qseven

All the features on the CQ7-A42 board are implemented according to the Qseven

compatible with Qseven

Spec. 2.0 modules.

The list of features that are effectively available depends on the configuration of the carrier board and of the Qseven

CQ7-A42 board is specially designed for being both an advanced development board, for skilled users who want to design their own carrier boards, and a good

solution for mass production, for customers whose needing are satisfied by this compact and versatile Carrier Board.

All the components mounted onboard are certified for industrial temperature range.
