Chapter: Overview Features
2 Overview
2.1 Features
The CB3056 is a highly complex 3,5-inch board which incorporates complete motherboard functionality.
It's based on Intel®'s QM67 chipset combined with an rPGA988B CPU socket for Intel® CPUs of the 2nd
Generation Core™ and Celeron® families. Modern DDR3 technology provides top-notch memory
performance, accommodating up to 16 GByte of RAM (DDR3-1066/1333/1600) via SO-DIMM204. It also
provides a PCI bus (via mPCI connector), a PCI-Express bus (via a 2x40 pin custom connector) and
additional peripheral devices such as four serial interfaces, two Gigabit Ethernet interfaces (LAN), four
SATA channels (two of which offering up to 6Gb/s), an audio interface (HDA 5.1), eleven USB channels,
and two DVI/HDMI connectors with CRT available through DVI-I, and DisplayPort available on a 30pin
I-PEX connector.

3 Connectors
This section describes all the connectors found on the CB3056.
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 CPU Socket
3.2 CPU Socket
The CB3056 board has an rPGA988B CPU socket accomodating certain models of Intel®’s 2nd
Generation Core™ and Celeron® family CPUs. The rPGA988B is a ZIF (Zero Insertion Force) socket,
which means that you can insert the processor without there being any resistance. There is only one
orientation in which the processor will fit into the socket. Once the processor is in place the fastening
screw must be tightened to ensure proper electrical contact.
The package type allows a maximum die temperature of 100 degrees Celsius and accords highest
possible security even in rough environment.
The processor includes a second level cache of up to 6 MByte, depending on which model is used.
Furthermore the processors offer many features known from the desktop range such as MMX2, serial
number, loadable microcode etc.
NOTE
Processors must be ordered separately. The board ships without a CPU.

Power Supply Chapter: Connectors
3.3 Power Supply
The power supply of the hardware module is realized via a 2x8-pin connector (Molex PS 43045-16xx,
mating connector: Molex PS 43025-16xx). The 12 volt supply is needed for PCI-Express cards and for the
fan connector. COM3 RXD and TXD can also be used for connecting a second power supply unit, e. g.
for UPS. As an ordering option SMBus signals SCL/SDA can be provided (replacing COM3 TXD/RXD).

Chapter: Connectors System
3.4 System
A number of signals for system control and for SMBus communication are provided through a 2x12 pin
connector (FCI 98424-G52-24LF). This connector combines signals for power button, reset, keyboard,
speaker, and several LEDs such as harddisk LED, and suspend LED, and three additional LEDs which
are driven by GPIOs. Of these three GPIO-LEDs, LED1 and LED2 are already provided with a series
resistor. SMBus capable devices can also be connected.

Memory Chapter: Connectors
3.5 Memory
Conventional SO-DIMM204 memory modules, as familiar from notebook computers, are used to equip
the board with memory. For technical and mechanical reasons it is possible that particular memory
modules cannot be employed. Please ask your distributor for recommended memory modules.
With currently available SO-DIMM204 modules a memory extension up to 16 GByte is possible
(DDR3-1066/1333/1600).
All timing parameters for different memory modules are automatically set by BIOS.

3.7 DVI/HDMI/DisplayPort
The CB3056 provides a second DVI interface which is realized as a 30pin flat cable header (I-PEX
Cabline-VS 20455-030E). Analog VGA is not available on this connector. However, an HDMI device or
DisplayPort device can be connected. The connector also carries an additional USB interface.

USB 1-4 Chapter: Connectors
3.8 USB 1-4
The USB channels 1 to 4 are available as standard USB connectors.
The USB channels support USB 2.0. You may note that the setting of USB keyboard or USB mouse
support in the BIOS-setup is only necessary and advisable, if the OS offers no USB-support. BIOS-setup
can be changed with a USB keyboard without enabling USB keyboard support. Running Windows with
these features enabled may lead to significant performance or functionality limitations.
Every USB interface provides up to 500 mA current and is protected by an electronically resettable fuse.

Chapter: Connectors Audio
3.11 Audio
Audio input and output functions can be accessed via a 2x5 pin connector (FCI 98424-G52-10LF). There
are two ways to use this connector. Default functionality is the familiar audio in, audio out, and
microphone. OS dependent device drivers can switch these signals to support a 5.1 output; thus in this
mode no audio input signals are available.
Signals "SPDIFI" and "SPDIFO" provide digital input and output. If a transformation to a coaxial or optical
connector is necessary this must be performed externally.
