ESD Precautions
Computer boards have integrated circuits sensitive to static electricity.
To prevent chipsets from electrostatic discharge damage, please take
care of the following jobs with precautions:
Do not remove boards or integrated circuits from their anti-static
packaging until you are ready to install them.
Before holding the board or integrated circuit, touch an unpainted
portion of the system unit chassis for a few seconds. It
discharges static electricity from your body.
Wear a wrist-grounding strap, available from most electronic
component stores, when handling boards and components.

Introduction
The AX12270 is the powerful engine of PC/104 form factor CPU
Module. It comes with high-performance VIA V4 complaint processors,
maximum up to 15 watts support (both C7 & Eden up to 1.5GHz), and
high integration core logic controller VIA CX700 and ITE8888G PCI-
to-ISA bridge that features Ultra Low Power V4 C7/Eden CPUs,
DualView with different content and resolution, USB DOM support as
SSD, and PC/104+ for both 16-bit ISA and 32-bit PCI expansion.
It is a PC/104 form factor board with support for one onboard system
memory DDR2 (up to 256MB), graphics UMA with maximum up to
64MB memory, and both CRT and LVDS (dual channel 24-bit) LCD. It
is equipped with four USB2.0 ports, one PATA IDE port, two serial
ports for RS-232 and RS-232/422/485, one P/S port for Keyboard/
Mouse, an interface for fast Ethernet, and a digital I/O.
The built-in Watchdog Timer has enhanced the system reliability that
achieves a unique feature to distinguish itself from other boards.
