1.1 Introduction
We are appreciating your purchase of AAEON's Embedded Technology
EXtended (ETX) product–the ETX-625.
Being an ETX compatible module, the ETX-625 was designed specially to
improve the quality and speed of your product development. It will provide
a more compact size and more flexibility for your various applications.
The features of the ETX-625 are based on the Intel®Ultra Low Voltage
Celeron®(or optional Low Power Pentium®III) processor combined with
VIA Twister and VT82C686B chipsets. It has one 144-pin SODIMM socket
that allows a system memory capacity up to 512MB with non-ECC SDRAM
modules. Hence, the ETX-625 can provide common PC peripheral
functions such as graphics, USB, serial, parallel ports, keyboard/mouse,
Ethernet, and IDE. The baseboard designer can optimize exactly which and
how these functions are implemented physically.
All of AAEON's ETX modules have a standard form factor and a standard
connector layout that carry a specified set of signals. By adopting this
standardization, the designers can create a single system of “baseboards”
that can accept present and future ETX modules. The baseboard designer
can optimize exactly how each of these functions is implemented physically.
Designers can place connectors precisely where needed for the application
on a baseboard designed to optimally fit a system’spackaging.

AAEON’s ETX system is your stepping-stone to a whole new world of
embedded product development. Once again, thank you for your purchase
of this AAEON product and we trust that your product development will
be swift, sure and successful!

2.1 Safety Precautions
Always completely disconnect the power cord from
your board whenever you are working on it. Do not
make connections while the power is on, because a
sudden rush of power can damage sensitive
electronic components.
Always ground yourself to remove any static charge
before touching the board. Modern electronic
devices are very sensitive to static electric charges.
Use a grounding wrist strap at all times. Place all
electronic components on a static-dissipative surface
or in astatic-shielded bag when they are not in the
chassis
