properly 110/220V before connecting the equipment to the
power inlet.
o Place the power cord in such a way that people cannot
step on it.
o Always unplug the power cord before inserting any add-on
card or module.
o If any of the following situations arises, get the equipment
checked by authorized service personnel:
o The power cord or plug is damaged.
o Liquid has penetrated into the equipment.
o The equipment has been exposed to moisture.

Product Overview
1
The VIA EPIA-N800 is a compact and highly integrated Nano-ITX
mainboard. The Nano-ITX form factor is 50% smaller than the
Mini-ITX form factor — enabling the creation of an exciting new
generation of small, ergonomic, innovative and affordable
embedded systems.
The VIA EPIA-N800 Nano-ITX mainboard is rich in I/O integration
and comes with an integrated VIA Nano 1.3+ GHz NanoBGA2
processor that boasts of ultra-low power consumption and cool
operation.
KEY COMPONENTS
VIA Nano 1.3+ GHz Processor
Due to its ultra cool, ultra quiet, and reliable performance, the VIA
Nano 1.3+ GHz NanoBGA2 processor is a perfect fit for compact
embedded systems that need a good performance per watt ratio.
With a maximum power envelope of 15 W, the VIA Nano
processor offers impressive power efficiency and highly effective
heat dissipation all within an ultra compact NanoBGA2 package
measuring just 21mm x 21mm.
VIA VX800 All-in-one System Processor
The VIA VX800 integrates a premium graphics engine, an HD
audio controller, a DDR2 memory controller, a 400MHz FSB
processor interface, and extensive I/O support in a single -chip
design.
Complementing the power-efficient VIA Nano processor, the
VX800 is based on a highly sophisticated power efficient
architecture that enables rich integration in a compact package
with a maximum power envelope of just 2.3 W.
