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 EP820 Series is an Intel®Pentium®M/Celeron®M CPU
equipped EP820 board with graphics, Fast Ethernet and audio
interface. With the designing of space-limited application, the EP820
Series makes the finest embedded Pentium®M board in existence,
using a newly standardized EPIC format, larger than a PC/104
module, yet smaller than an EBX board.
EP820 Series can be adapted for Intel®low power consumption
Pentium®M microprocessors. To simplify the system integration, it
provides users with super I/Os, XVGA, LCD, Ethernet and solid state
disk that makes all on one single board. There comes with the unique
embedded feature that two serial ports (1 x RS-232, 1 x RS-
232/422/485) with +5V/12V power capability allow the adoption of an
extensive array of PC peripherals. The industrial-grade construction of
EP820 Series allows your system to endure the continuous operation
in hostile environments where require most stability and reliability.
The system dependability of EP820 series is highly enhanced by a
special industrial feature of the built-in Watchdog Timer, which makes
the board outstanding among others.
