ESD Precautions
Integrated circuits on computer boards are sensitive to static
electricity. To avoid damaging chips from electrostatic
discharge, observe the following precautions:
Do not remove boards or integrated circuits from their anti-static
packaging until you are ready to install them.
Before handling a board or integrated circuit, touch an unpainted
portion of the system unit chassis for a few seconds. This helps to
discharge any static electricity on your body.
Wear a wrist-grounding strap, available from most electronic
component stores, when handling boards and components.

Introduction
The SBC84820 is an Intel®Pentium®M/ Celeron™M CPU
equipped Capa board with graphics, Fast Ethernet and audio
interface. Designed with the space-limited applications in mind,
the SBC84820 is practically the finest embedded Pentium®M
board that exists. Using a standardized format conforming to
the size of a 3.5”HARD DISK drive, SBC84820 Series adapt
an Intel®low power consumption Pentium®M microprocessors.
To simplify system integration, it packs provisions such as
super I/Os, XVGA, LCD, Ethernet, solid state disk, all on a
single board. Unique embedded features such as 2 serial ports
(1 x RS-232, 1 x RS-232/422/485, COM3/4 are optional) with
+5V/12V power capability and that allow adoption of an
extensive array of PC peripherals. The industrial-grade
construction of SBC84820 series allows your system to endure
the continuous operation in hostile environments where
stability and reliability are basic requirements. System
