LV-651 User’s Manual Introduction

Product Overview 7

Chapter 1 <Introduction>

1.1 <Product Overview>

LV-651 is the Mini-ITX motherboard with AMD Geode LX800 platform, with onboard VGA,

AC97 audio, Giga LAN interface. Based on the AMD Geode LX800 processor, the board

provides many advanced features for reduced power consumption, fanless design and high

cost/price rate of production.

Low Power Consumption

Based on the AMD Geode LX800@500MHz processor onboard, it only takes up to 3.8W at

maximum powering, and is completely suitable for fanless design. Without any cooling fan

onboard, it can avoid the heat problem when the cooler failed in accidence.

Onboard TTL interface

Based on the AMD Geode LX800@500Mhz of integrated graphics, the board provides

onboard graphics with up to 256 MB of frame buffer, 18-bit/24-bit LVDS and 24-bit TTL

interfaces.

Embedded Component

Due to the low profile design, the board provides CF card socket for flash disk with porting

embedded OS and up to DDR SDRAM.

Single Voltage Input

The board only requires DC 8~24V or standard 20-pin ATX power supply input; user’s can

easily connect the board with an adapter without the huge power supply.
