VIA EPIA LN-Series Overview
The VIA EPIA LN-Series Mini-ITX Mainboard is an ultra compact native x86 platform
optimized for today's demanding embedded and productivity applications. The mainboard is
based on the VIA CN700 chipset featuring an embedded hardware MPEG-2 accelerator and
integrated VIA UniChrome™ Pro 2D/3D graphics for rich digital media performance. With
the sizable memory bandwidth of DDR2 533MHz SDRAM DIMM and the high data transfer
speed of ATA-133 and further enhanced by support of 8-Channel AC’97 codec for Smart 5.1
surround sound and SPDIF, the VIA EPIA LN-Series delivers the increased performance
levels required by today’s embedded digital media applications.
The latest in high-bandwidth connectivity is supported with six USB 2.0 ports, as well as a
COM port and has one 10/100 Fast Ethernet port for extended broadband connectivity. The
VIA EPIA LN-Series also has one PCI slot for expandability options. The VIA EPIA LN-Series
is compatible with a full range of Mini-ITX chassis as well as FlexATX and MicroATX
enclosures and power supplies.
The VIA EPIA LN-Series is fully compatible with Microsoft® and Linux operating systems and
is available in a variety of configurations, including the latest VIA C7™ V4 Bus NanoBGA2
processor for small, low power and secure x86 processor platforms.
