General Safety Precautions
This product was developed for fault-free operation. Its design provides conformance to all related
safety requirements. However, the life of this product can be seriously shortened by improper
handling and incorrect operation. That is why it is necessary to follow general safety and
operational instructions below.
Warning!
All operations on this device must be carried out by sufficiently
skilled personnel only.
Warning!
When handling this product, special care must be taken not to hit
the heatsink (if installed) against another rigid object. Also, be
careful not to drop the product, since this may cause damage
to the heatsink, CPU or other sensitive components as well.
Please, keep in mind that any physical damage to this product
is not covered under warranty.
Note:
This product is guaranteed to operate within the published
temperature ranges and relevant conditions. However, prolonged
operation near the maximum temperature is not recommended by
Fastwel or by electronic chip manufacturers due to thermal stress
related failure mechanisms. These mechanisms are common to all
silicon devices, they can reduce the MTBF of the product by
increasing the failure probability. Prolonged operation at the lower
limits of the temperature ranges has no limitations.
Caution, Electric Shock!
Before installing this product into a system and before installing
other devices on it, always ensure that your mains power is switched
off.
Always disconnect external power supply cables during all handling
and maintenance operations with this module to avoid serious
danger of electrical shock.

Unpacking, Inspection and Handling
Please read the manual carefully before unpacking the module or mounting the device into your
system. Keep in mind the following:
ESD Sensitive Device!
Electronic modules and their components are sensitive to static
electricity. Even a non-perceptible by human being static discharge
can be sufficient to destroy or degrade a component's operation!
Therefore, all handling operations and inspections of this product
must be performed with due care, in order to keep product integrity
and operability:
 Preferably, unpack or pack this product only at EOS/ESD safe workplaces. Otherwise, it is
important to be electrically discharged before touching the product. This can be done by
touching a metal part of your system case with your hand or tool. It is particularly important
to observe anti-static precautions when setting jumpers or replacing components.
 If the product contains batteries for RTC or memory back-up, ensure that the module is not
placed on conductive surfaces, including anti-static mats or sponges. This can cause short-
circuit and result in damage to the battery and other components.
 Store this product in its protective packaging while it is not used for operational purposes.
Unpacking
The product is carefully packed in an antistatic bag and in a carton box to protect it against
possible damage and harmful influence during shipping. Unpack the product indoors only at a
temperature not less than +15°C and relative humidity not more than 70%. Please note, that if the
product was exposed to the temperatures below 0°Сfor a long time, it is necessary to keep it at
normal conditions for at least 24 hours before unpacking. Do not keep the product close to a heat
source.
Following ESD precautions, carefully take the product out of the shipping carton box. Proper
handling of the product is critical to ensure correct operation and long-term reliability. When
unpacking the product, and whenever handling it thereafter, be sure to hold the module preferably
by the front panel, card edges or ejector handles. Avoid touching the components and connectors.
Retain all original packaging at least until the warranty period is over. You may need it for
shipments or for storage of the product.
Initial Inspection
Although the product is carefully packaged, it is still possible that shipping damages may occur.
Careful inspection of the shipping carton can reveal evidence of damage or rough handling. Should
you notice that the package is damaged, please notify the shipping service and the manufacturer
as soon as possible. Retain the damaged packing material for inspection.
After unpacking the product, you should inspect it for visible damage that could have occurred
during shipping or unpacking. If damage is observed (usually in the form of bent component leads
or loose socketed components), contact Fastwel's official distributor from which you have
purchased the product for additional instructions. Depending on the severity of the damage, the
product may even need to be returned to the factory for repair. DO NOT apply power to the product
if it has visible damage. Doing so may cause further, possibly irreparable damage, as well as result
in a fire or electric shock hazard.

Introduction CPB904
1 Introduction
This document presents general information on CPB904 processor module, the details of its proper
and safe installation, configuration and operation.
1.1 Module Introduction
CPB904 is an ETX computer-on-module (COM), highly integrated and compact single board
computer for use in systems requiring low power consumption and wide operating temperature
range. All I/O signals as well as full realization of ISA and PCI buses are mapped to four standard
high density, low profile connectors on the bottom side of the module. CPB904 is designed for use
in applications being mounted on an ETX baseboard.
CPB904 is based on low power AMD Geode LX800 CPU and AMD CS5536AC I/O companion.
Dynamic Memory interface supports 64-bit DDR SDRAM via SODIMM socket and soldered 128 or
256 MB memory bank.
All key components including CPU, chipset, memory, and periphery controllers are soldered
on-board providing excellent vibration stability and increased efficiency of protective conformal
coating.
CPB904 offers wide variety of data display capabilities. It allows simultaneous operation of
standard VGA interface, 24-bit LVDS interface, and 18-bit interface for TFT or DSTN LCD panels
connection. In addition TV output is available.
Data storage subsystem is based on single-channel IDE controller, that is able to drive up to two
IDE devices: two external hard drives, CompactFlash card.
For data exchange, CPB904 uses one independent Fast Ethernet port, three COM ports, four USB
2.0 ports, IrDA port, and parallel port combined with FDD and with 17 programmable discrete
input/output lines.
System control and management capabilities of CPB904 include watchdog timer, reserved BIOS,
and possibility to save system configuration and emergency parameters in FRAM chip.
CPB904 is manufactured in three versions: CPB904-01 (256 MB of soldered system memory),
CPB904-02 (512 MB soldered), and CPB904-03 with SODIMM socket for up to 512 MB DDR
SDRAM.
CPB904 is designed for operation within industrial temperature range from –40 C to +85°C.
CPB904 supports wide range of operating systems – Fastwel DOS (MS DOS-compatible),
Windows XP embedded, QNX 4.25 and 6.3x, Linux 2.4, and Windows CE.NET 4.2.
