1/ Introduction
This manual describes the mITX-BDW-U board made by Kontron. This board will also be denoted mITX-BDW-U within
this user guide.
The mITX-BDW-U board is based on the BDW-U chipset and supports the 5th generation Intel® Broadwell i7 -, i5 -, i3
2Core mobile processors. See Chapter 3.3 Processor Support Table, for specific details.
Use of this user guide implies a basic knowledge of PC-AT hard- and software. This manual focuses on describing the
mITX-BDW-U board’s special features and is not intended to be a standard PC-AT textbook.
New users are recommended to study the short installation procedure within this user guide before switching-on the
power.
Configuration and setup of the CPU board is either done automatically or manually by the user via the BIOS setup
menus.
Latest revision of the user guide, datasheet, thermal simulations, BIOS, drivers, BSP’s (Board Support Packages),

2/ Installation Procedure
2.1. Installing the Board
Follow these steps to get the board up and running. If the board already has components like RAM and CPU cooler
mounted, leave out the relevant steps below.
1. Turn off the PSU (Power Supply Unit)
Turn off PSU (Power Supply Unit) completely (no mains power connected to the PSU)
or leave the Power Connectors unconnected while configuring the board. Failure to do so
might damage components (RAM, LAN cards etc.). Only use a standard ATX PSU. Running the
board with a non-compliant ATX PSU may damage the board within minutes .
2. Insert the DDR3L SO-DIMM 204-pin SO-DIMM module(s)
Be careful to push it in the slot(s) before locking the tabs. For a list of approved DDR3L SO-DIMMs contact your
Distributor or FAE. For more information refer to chapter “System Memory Support”.
3. Cooler Installation
The mITX-BDW-U comes with a passive heatsink pre-installed and a separate fan, that can be mounted onto the
heatsink, should the system require additional airflow. Connect Cooler Fan electrically to the FANCPU connector.
4. Connecting Interfaces
Insert all external cables for hard disk, keyboard etc. A monitor must be connected in order to change BIOS settings.
5. Connect and turn on PSU
Connect PSU to the board by the ATX+12 V- 4p connector or alternatively connect a 19 V power adapter to the I/O
power jack.
6. Power Button
If the board does not start by itself when switching on the ATX PSU AC mains, then follow these instructions to start
the board. Install the Always On Jumper in the Always On position or toggle the PWRBTN_IN# signal (available in the
FRONTPNL connector), by momentary shorting pins 16 (PWRBTN_IN#) and pin 18 (GND). A “normally open” switch is
recommended.
7. BIOS Setup
Enter the BIOS setup by pressing the <F2> key during boot up.
Enter “Exit Menu” and Load Setup Defaults.
Refer to the “BIOS Configuration / Setup“ section of this manual for details on BIOS setup.
To clear all BIOS settings, including Password protection, activate “Load Default BIOS
Settings” Jumper for approximately 10 sec (without power connected).
8. Mounting the board in chassis
When mounting the board to the chassis etc. take note that the board contains components
on both sides of the PCB that can easily be damaged if board is handled without reasonable
care. A damaged component can result in malfunction or no function.
When fixing the Motherboard on a chassis it is recommended to use screws with integrated washer and a diameter of
approximately 7 mm. Do not use washers with teeth, as they can damage the PCB and cause short circuits.

mITX-BDW-U – User Guide, Rev. 1.6
www.kontron.com // 12
2.2. Chassis Safety Standards
When designing the chassis interface connectors, take care that the connectors fulfil the IEC60950 standard.
mITX-BDW-U (T4006) users must evaluate the end-product to ensure that the requirements of the 60950-1 safety
standard are met:
The motherboard must be installed in a suitable mechanical, electrical and fire enclosure.
The system, in its enclosure, must be evaluated for temperature and air flow considerations.
The motherboard must be powered by a CSA or UL approved power supply that limits the maximum input current
to 10A via external barrel-type 19 VDC connector, and to 16 A via internal square 12 VDC ATX connector.
For interfaces having a power pin such as external power or fan, ensure that the connectors and wires are
suitably rated. All connections from/to the product shall be with SELV circuits only.
Wires have suitable rating to withstand the maximum available power.
The enclosure of the peripheral device fulfils the fire protecting requirements of IEC60950.

3.4. System Memory Support
The mITX-BDW-U has two DDR3L SO-DIMM sockets. The sockets support the following memory features:
2x DDR3L, 1.35 V, SO-DIMM 204-pin
Dual-channel with one SO-DIMM per channel
From 1 GByte and up to 2x 8 GByte.
If using 32bit OS, less than 4 GB are displayed in the system
(Shared Video Memory/PCI resources is subtracted).
Single/dual rank unbuffered 1333/1600MT/s (PC3-10600/PC3-12800)
SPD timings supported
ECC not supported
The installed DDR3L SO-DIMM should support the Serial Presence Detect (SPD) data structure. This allows the BIOS to
read and configure the memory controller for optimal performance. If non-SPD memory is used, the BIOS will attempt
to configure the memory settings, but performance and reliability may be impacted.

Memory Operating Frequencies
Regardless of the SO-DIMM type used, the memory frequency will either be equal to or less than the processor
system bus frequency. For example, if DDR3L 1600 memory is used with a 1333 MHz system bus frequency processor,
the memory clock will operate at 167 MHz. The table below lists the resulting operating memory frequencies based on
the combination of SO-DIMMs and processor.

1060-2520
2 GByte DDR3L-1600, PC3-12800
1055-9939

4 GByte DDR3L-1600, PC3-12800
1055-9941
1060-2524 8 GByte DDR3L-1600, PC3-12800 1055-9942
Memory modules have, in general, a much lower longevity than embedded motherboards, and therefore EOL of
memory modules can be expected several times during the lifetime of the motherboard. Kontron guarantees that the
above Part Numbers (PNs) will be maintained by replacing EOL memory modules with other similar modules.
As a minimum, it is recommend to use Kontron memory modules for prototype system(s) in order to prove the
stability of the system and for reference.
For volume production you might want to test and qualify other types of RAM. In order to qualify RAM it is
recommend to configure 3 systems running a RAM Stress Test program in a heat chamber at 60° C for a minimum of
24 hours.
3.5. mITX-BDW-U Graphics Subsystem
The mITX-BDW-U equipped with Intel ® i3, i5 or i7 processor, supports Intel ® Gen 8 HD Graphics core. All
mITX-BDW-U versions support three displays pipes. The DP interface supports the DisplayPort 1.2a specification. The
