The Graphics ClientM (GCM) is a low-power single-board computer based on the
Marvell® PXA320 processor. The PXA320 processor integrates scalable generalpurpose processing, 2D graphics acceleration, and wireless technology to provide
hardware-accelerated graphics display and high-powered computing capabilities. The
GCM is ideal for running graphics-intensive applications, especially those requiring
wireless connectivity, and is targeted towards hand-held, medical, fleet management, and
embedded markets.
In addition to industry-standard interfaces, the GCM includes the ADSmartIO™. The
ADSmartIO extends GCM capabilities by providing a wide array of customizable
functions and I/O.
This manual provides details about the various features of the GCM and about how they
create a system that meets your application needs. It is intended for embedded system
integrators and software application developers. Design details apply to the revision listed
in Appendix C – Board Revision, page 57.
Introduction
Block Diagram
The following diagram illustrates the system organization of the GCM. The functionalities
shown with dotted lines or labelled as optional are available as volume production
options. The following sections provide further details about these various options.
For detailed mechanical drawings of the GCM, see Mechanical, page 26.

Handling Your Board Safely
Anti-Static Handling
The GCM contains CMOS devices that could be damaged by electrostatic discharge
(ESD). Observe industry-standard electronic handling procedures when handling the
board. Where possible, work on a grounded anti-static mat. At a minimum, touch an
electrically grounded object before handling the board or touching any components on
the board.
Packaging
Please ensure that, should a board need to be returned to Eurotech, it is adequately
packed, preferably in the original packing material.
Electromagnetic Compatibility
The GCM is classified as a component with regard to the European Community
Electromagnetic Compatibility (EMC) regulations. Because Eurotech supplies only the
single-board computer and not fully integrated systems, Eurotech cannot provide
meaningful system-level emissions test results. It is the responsibility of the user to
ensure that systems using the GCM are compliant with the appropriate EMC standards.
RoHS Compliance
The European RoHS Directive (Restriction on the use of certain Hazardous Substances –
Directive 2002/95/development system) limits the amount of six specific substances
within the composition of the product. The GCM fully complies with the RoHS directive.
A ful l RoHS Compliance Materials Declaration Form for the GCM is included as Appendix
B – RoHS Compliance, page 56. Further information regarding RoHS compliance is
available on the Eurotech web site at www.eurotech.com
