1.1 Introduction
We are appreciating your purchase of AAEON's Embedded
Technology EXtended (ETX) product –the ETX-821.
Being an ETX compatible module, the ETX-821 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-821 are based on the Intel®Ultra Low
Voltage Celeron®M or LV Pentium®Mprocessor combined with
Intel®852/855 (GM/GME) and ICH4 chipsets. It has one 200-pin
SODIMM socket that allows a system memory capacity up to 1GB
with DDR SDRAM module. Hence, the ETX-821 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’s packaging.
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!
