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.

CHAPTER 1
INTRODUCTION
The PICO820 is a Pico-ITX board with support for Intel® ATOM™
processor Z500 Series, and integrates chipset Intel®System
Controller Hub US15W that deliver outstanding system performance
through high-bandwidth interfaces, multiple I/O functions for interactive
applications and various embedded computing solutions. The board
has one 200-pin unbuffered SODIMM sockets for DDR2 400/533 MHz
SO-DIMM memory, maximum memory capacity up to 2GB. It also
features Gigabit/Fast Ethernet, one serial ATA port, four USB 2.0 high
speed compliant, built-in high definition audio codec that can achieve
the best stability and reliability for industrial applications. It provides
you with unique embedded features, such as two serial ports (2x RS-
232) and Pico-ITX form factor that applies an extensive array of PC
peripherals. The board can be enhanced by its built-in watchdog timer,
a special industrial feature not commonly seen on other motherboards.
