LV-671 User’s Manual Introduction
Product Overview 9
Chapter 1 <Introduction>
1.1 <Product Overview>
LV-671 is an all-in-one industrial compact Pentium-M level motherboard based on Mini-ITX
form factor at 170 x 170 mm of dimension. Based on Intel 855GME and ICH4 chipset,
LV-671 offers the compact, embedded, value and high performance solution with Intel
Pentium-M CPU, 400MHz of FSB, 1GBytes DDR200/266/333 SDRAM with ECC, Intel
855GME GMCH built-in Intel Extreme Graphics 2, Intel PRO/1000+ LAN, Hi-Speed USB
2.0, 5.1 channel and S/P DIF 3D audio, 18/24-bit dual channel LVDS, GPIO and
embedded flash disk interfaces.
Low Power Consumption Solution
Based on Intel 855GME chipset and Intel Pentium M/Celeron M processor, the board
requires lower power consumption than Pentium 4 –M processors. The Intel Pentium M
integrates 512KB/1MB/2MB of L2 cache, so it provides better performance than before.
Dual Display Architecture
Intel 855GME supports two DAC for display interface; users can apply two display
devices for dual display clone or extended desktop display. With this feature, system
integrator can use this board for Kiosk, ATM, or industrial control machines.
5.1 Channel AC97 Audio
LV-671 integrates a REALTEK 5.1 channel AC97 codec; users can enjoy the live
surround sound through 5.1 channel speakers. LV-671 also has an S/PDIF jack for digital
sound outputting.
Hi-Speed USB 2.0 Interface
Intel ICH4 built-in Hi-Speed USB 2.0 controller let LV-671 offer up to 480Mbps of
transferring rate.
Card Bus and Embedded Flash Disk
TheLV-671 support PCMCIA Type I/II enable you can simply use the wireless LAN
module or other extended devices, the Compact Flash interface and IDE1 with DOM
support can let you port any embedded system onboard.
Mini-PCI and Mini-AGP interface
With Mini-PCI interface, users can add a wireless LAN module or video capture
module for powerful communication solutions. With Mini-AGP interface, users can apply
the AGP graphic card or additional video output module such as HDTV or DVI.
