”
SBC with an on-board embedded
5x86 class CPU , NS Geode GX1-300 processor. With this board, system
engineers will be able to upgrade 386-based or 486-based to 586-level
without some additional worries, because a NS Geode GX1-300 processor
and 64MB SDRAM are mounted on 3304280 . No longer worry about the
CPU installation ,don ’t n eed to set any jumpers of speed or voltage of
processor . And the fan is not necessary for NS Geode Gx1-300 , the MTBF
worries will be reduced . DRAM on-board will improve the ability of the anti-
vibration . 3304280 has the good reliability for system designer .
With its ultra low power, rich levels of integration, advanced multimedia

Warning
Single Board Computers and their components contain very
delicate Integrated Circuits (IC). To protect the Single Board
Computer and its components against damage from static
electricity, you should always follow the following precautions
when handling it :
1. Disconnect your Single Board Computer from the power source
when you want to work on the inside
2. Hold the board by the edges and try not to touch the IC chips, leads
or circuitry
3. Use a grounded wrist strap when handling computer components.
4. Place components on a grounded antistatic pad or on the bag that
came with the Single Board Computer, whenever components are
separated from the system

Watchdog Timer
Watchdog Output
The onboard watchdog timer can be disable by jumper setting or enable for
either reboot by system RESET .The Jumper is on the carrier board.
Even if enabled by jumper setting upon boot the watchdog timer is always
inactive. To initialize or refresh the watchdog timer writing of port 444H is
sufficient. To disable the watchdog time read port 44H.
Status Action
Enable/refresh the Watchdog Timer I/O Write 444H
Disable the Watchdog Timer. I/O Read 044H
After the watchdog timer has been initialized by reading port 444H, it has to
be strobed at preconfigured intervals to keep it from issuing a RESET or NMI.
The watchdog timer timeout intervals are set by software programming.
Timeout Values
Timout values are programmed. The watchdog timer supports 128 steps.
use the table on the next page to find the hexidecimal value that needs to be
passed on to get the correct timer interval. Look subsequntly at the program
example how to pass the value to the watchdog timer.
