Introduction
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 TFT/LVDS LCD 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 TFT
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.

Hardware Setup
To setup the LCD, you need the component below:
1. A panel with LVDS interfaces.
2. An inverter for panel’s backlight power.
3. A LCD cable and an inverter cable.
For the cables, please follow the pin assignment of the connector to make a cable, because
every panel has its own pin assignment, so we do not provide a standard cable; please find a
local cable manufacture to make cables.
LCD Installation Guide:
1. Preparing the LV-651, LCD panel and the backlight inverter.
2. Please check the datasheet of the panel to see the voltage of the panel, and set the
jumper JVLCD to +5V or +3.3V.
3. You would need a LVDS type cable.
