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 EP812 is an Intel®Pentium®M/Celeron™M CPU equipped
Capa board with graphics, Dual Fast Ethernet and audio
interface. Designed with the space-limited applications in mind,
the EP812 is practically the finest embedded Pentium®M board
that exists.EP812 Series adapt an Intel®low power
consumption Pentium®M microprocessors. To simplify system
integration, it packs provisions such as super I/Os, UXGA, 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) with +5V/12V power capability and that allow
