CHAPTER 1
Specifications
The ultra-compact and highly integrated VIA EPIA-PX Pico-ITX
mainboard is the smallest form-factor available today. Through a
high level of integration, the Pico-ITX measures at only 25% of
the size of a Mini-ITX mainboard. The mainboard enables the
creation of an exciting new generation of small, ergonomic,
innovative and affordable embedded systems.

Installation
This chapter provides you with information about hardware
installation procedures. It is recommended to use a grounded wrist
strap before handling computer components. Electrostatic discharge
(ESD) can damage some components.

CPU
The VIA EPIA-PX Pico-ITX mainboard can support VIA C7 NanoBGA2
processor. The processor requires a heatsink with fan for 1.0GHz SKU.
CPU Fan: CPU_FAN
The CPU_FAN runs on +5V and maintain CPU cooling. When connecting the
wire to the connectors, always be aware that the red wire (positive wire)
should be connected to +5V. The black wire is Ground and should always be
connected to GND.

533 SDRAM memory modules and supports memory sizes up to 1GB.
Insert the SODIMM module at a 45 degree angle.
Push the SODIMM module back towards the board until the clips lock the
module in place.
Available DDR2 SDRAM Configurations
Refer to the table below for available DDR2 SDRAM configurations on the
mainboard.

CONNECTING THE POWER SUPPLY
The VIA EPIA-PX Pico-ITX mainboard supports a Pico-ITX power supply for
the power system. Before inserting the power supply connector, always
make sure that all components are installed correctly to ensure that no
damage will be caused.
Pico-ITX 12-Pin Power Connector
To connect the power supply, make sure the power plug is inserted in the
proper orientation and the pins are aligned. Then push down the plug firmly
into the connector.
