Chapter: Overview Features
2 Overview
2.1 Features
The CB4055 is a highly complex computer motherboard in the PC/104™ form factor, complying with the
state-of-the-art "PCIe/104™" standard. It's based on Intel® CPUs of the 2nd Generation Core™ and
Celeron® families (BGA, embedded) combined with the QM67 PCH. Modern DDR3 technology provides
top-notch memory performance, accomodating up to 4 GByte of RAM (DDR3-1066/1333/1600) via
SO-DIMM204. PCI-Express is available through the PCI/104-Express Type 1 connector, offering one x16
connection and four x1 lanes for connecting all kinds of expansion cards in a PCIe/104™ stack-down
fashion. For connecting graphics devices, several interfaces are available: CRT, LVDS, HDMI,
DisplayPort. Additional interfaces include two serial ports, two Gigabit Ethernet interfaces (LAN), two
SATA channels (up to 6Gb/s), an audio interface (HDA 7.1), and ten USB channels. There are also 16
discrete programmable GPIO signals available.

3 Connectors
This section describes all the connectors found on the CB4055.
CAUTION
For most interfaces, the cables must meet certain requirements. For instance, USB 2.0 requires twisted
and shielded cables to reliably maintain full speed data rates. Restrictions on maximum cable length are
also in place for many high speed interfaces and for power supply. Please refer to the respective
specifications and use suitable cables at all times.

Chapter: Connectors Power Supply
3.2 Power Supply
The power supply of the hardware module is realized via a 2x5-pin connector (Molex PS 43045-10xx,
mating connector: Molex PS 43025-10xx). Both 5V VCC/SVCC and 12V need to be provided. The 12V
input can optionally be tied to 5V if 12V is not required by attached peripherals. It cannot, however, be left
unconnected.
CAUTION
The CB4055 includes circuitry that will notify an intelligent power supply to shut down if the processor
reaches a critical temperature. This is achieved by deasserting the (low-active) PS_ON# signal found on
the SM-Bus connector. When PS_ON# is no longer pulled low, an intelligent power supply would take this
as a signal to shut down power. For this to work, PS_ON# must be connected to the power supply's
PS_ON input. If PS_ON# is not otherwise connected, the CB4055 can be damaged beyond repair if a
thermal shutdown event occurs. In rare instances, if power is not shut down, the board will continue to
heat up until failure occurs.
NOTE
Since this is a 90 degree connector, the symbol in the drawing below represents the connector face as
seen from the side (PCB on bottom) rather than from above.

3.3 System/SM-Bus
Both SM-Bus signals, and signals for PS/2 keyboard, PS/2 mouse and speaker are provided through a
2x9pin connector (FCI 98424-G52-18LF, mating connector e.g. FCI 90311-018LF). For the #PSON
signal, please refer to the cautionary note in the chapter "Power Supply" (p. 16).

Chapter: Connectors Memory
3.4 Memory
There is one conventional SO-DIMM204 socket available to equip the board with memory
(DDR3-1066/1333/1600). It is located on the bottom side of the board. For technical and mechanical
reasons it is possible that particular memory modules cannot be employed. Please ask your sales
representative for recommended memory modules.
With currently available SO-DIMM modules a memory extension up to 4 GByte is possible. The timing
parameters for different memory modules are automatically set by BIOS.

3.6 DVI/HDMI
The CB4055 provides a DVI/HDMI interface which is realized as a 2x9pin header (FCI 98424-G52-18LF,
mating connector e.g. FCI 90311-018LF).

Chapter: Connectors DisplayPort
3.7 DisplayPort
The CB4055 offers a DisplayPort interface which is realized as 2x10pin connector (FCI 98424-G52-20LF,
mating connector e.g. FCI 90311-020LF). This interface can also be operated in HDMI/DVI mode. To
achieve this, pin 11 must be connected to 3.3V (e.g. pin 3).

VGA Chapter: Connectors
3.8 VGA
The CRT-VGA signals are provided by a 2x5pin connector (FCI 98424-G52-10LF, mating connector e.g.
FCI 90311-010LF).
This interface allows the connection of a standard VGA-monitor. I2C communication is supported.

Chapter: Connectors LCD
3.9 LCD
The LCD is connected via two 15 pin connectors (Hirose DF13-15P-1.25DSA, mating connector:
DF13-15S-xxx). The power supply for the display is also provided through these connectors. The CB4055
board only supports displays with LVDS interface. For displays with digital interface an extra receiver
board is available. There is no support for DSTN displays.
With the LVDS interface it is possible to trigger LVDS displays with a maximum of 24 Bit colour depth
and one or two pixels per clock. For single pixel displays only one connector is necessary. However, if
you want to read the display's EDID data the second connector must be connected.
The display type can be chosen over the BIOS setup. Please contact your sales representative regarding
an appropriate cable to connect your display.
The following table shows the pin description for the first bit ("even" pixel).
