SDML-WLU0 Series -- User Guide, Rev. 1.0
For Your Safety
Your new Kontron product was developed and tested carefully to provide all features necessary to ensure its
compliance with electrical safety requirements. It was also designed for a long fault-free life. However, the life
expectancy of your product can be drastically reduced by improper treatment during unpacking and installation.
Therefore, in the interest of your own safety and of the correct operation of your new Kontron product, you are
requested to conform with the following guidelines.
High Voltage Safety Instructions
As a precaution and in case of danger, the power connector must be easily accessible. The power connector is the
product’s main disconnect device.
Warning
All operations on this product must be carried out by sufficiently skilled personnel only.
Electric Shock!
Before installing a non hot-swappable Kontron product into a system always ensure that
your mains power is switched off. This also applies to the installation of piggybacks. Serious
electrical shock hazards can exist during all installation, repair, and maintenance operations
on this product. Therefore, always unplug the power cable and any other cables which
provide external voltages before performing any work on this product.
Earth ground connection to vehicle’s chassis or a central grounding point shall remain
connected. The earth ground cable shall be the last cable to be disconnected or the first
cable to be connected when performing installation or removal procedures on this product.
Special Handling and Unpacking Instruction
ESD Sensitive Device!
Electronic boards and their components are sensitive to static electricity. Therefore, care
must be taken during all handling operations and inspections of this product, in order to
ensure product integrity at all times.
Do not handle this product out of its protective enclosure while it is not used for operational purposes unless it is
otherwise protected.
Whenever possible, unpack or pack this product only at EOS/ESD safe work stations. Where a safe work station is not
guaranteed, it is important for the user to be electrically discharged before touching the product with his/her hands
or tools. This is most easily done by touching a metal part of your system housing.
It is particularly important to observe standard anti-static precautions when changing piggybacks, ROM devices,
jumper settings etc. If the product contains batteries for RTC or memory backup, ensure that the product is not placed
on conductive surfaces, including anti-static plastics or sponges. They can cause short circuits and damage the
batteries or conductive circuits on the product.

SDML-WLU0 Series - User Guide, Rev. 1.0
1/ Introduction
This user guide describes the SDML-WLU0 Series module made by Kontron. This module will also be denoted SDMLWLU0 Series within this user guide.
Use of this user guide implies a basic knowledge of PC-AT hardware and software. This user guide focuses on
describing the SDML-WLU0 Series module's special features and is not intended to be a standard PC-AT textbook.
New users are recommended to study the short installation procedure stated in the following chapter before
switching on the power.
All configuration and setup of the CPU board is either carried out automatically or manually by the user via the BIOS
setup menus.
Latest revision of this user guide, datasheet, thermal simulations, BIOS, drivers, BSP's (Board Support Packages),
mechanical drawings (2D and 3D) can de download from Kontron's Web Page.

SDML-WLU0 Series - User Guide, Rev. 1.0
2/ Installation Procedures
2.1. Installing the Module
ESD Sensitive Device!
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry.
Wear ESD-protective clothing and shoes
Wear an ESD-preventive wrist strap attached to a good earth ground
Check the resistance value of the wrist strap periodically (1 MΩ to 10 MΩ)
Transport and store the module in its antistatic bag
Handle the module at an approved ESD workstation
Handle the module only by the edges
To get the module running follow these steps. If the module shipped from KONTRON already has components like
RAM and CPU cooler mounted, then skip the relevant steps below.
An Intel® SDM ready display or power supply daughter card is required to proceed the
following steps.
In case of a display compatible with Intel® SDM specifications
1. Turn off the main power switch
Turn off the main power switch on the display and withdraw the module from the display if it has been installed.
2. Insert the DDR4 2400 / 2133 module(s)
Be careful to push the memory module(s) in the slot(s) before locking the tabs.
3. Connect interfaces
Install M.2 SSD if needed. Insert the module into the display. Connect all external cables for keyboard etc. in order
to change BIOS settings.
4. Power on the module
Turn on the main power switch on the display.
5. BIOS setup
Enter the BIOS setup by pressing the <DEL> key during boot up.
Enter "Exit Menu" and Load Setup Defaults.
In case of a power supply daughter card compatible with Intel® SDM specifications
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 module if it has been
connected to the power supply daughter card. Otherwise, components (RAM, LAN cards
etc.) might get damaged. Make sure to use a proper PSU depending on the daughter card
used with suitable cable kit and PS-ON# active.
The power supply unit shall comply with the requirements as defined in IEC 62368-1
according Clause 6.2.2 to power source category PS2 "Limited Power Source".

3.5. Processor Support
The SDML-WLU0 Series is designed to support 8th Generation Intel® Core™ U-Series and Celeron® 4000 Series
Processors. The BGA CPU is remounted from factory. Kontron has defined the module versions as listed in the
following table. Other versions are expected at a later date.

Sufficient cooling must be applied to the CPU in order to remove the effect as listed as TDP (Thermal Design Power) in
above table. The sufficient cooling is also depending on the worst case maximum ambient operating temperature and
the actual worst case load of processor.

3.6. System Memory Support
The SDML-WLU0 Series has two DDR4 SO-DIMM sockets. The sockets support the following memory features:
2x DDR4 SO-DIMM 260-pin
Dual-channel with 1x SO-DIMM per channel
Up to 64 GB
SPD timing supported
ECC not supported
The installed DDR4 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, or the module may not be able to
boot totally.
3.6.1. Memory Operating Frequencies
In all modes, the frequency of system memory is the lowest frequency of all the memory modules placed in the
system. Each memory module's frequency can be determined through the SPD registers on the memory modules.
The table below lists the resulting operating memory frequencies based on the combination of SO-DIMMs and
processor.

Memory modules have in general a much lower longevity than smart display modules, and therefore EOL of memory
modules can be expected several times during lifetime of the smart display modules.
As a minimum it is recommend using Kontron memory modules for prototype system(s) in order to prove stability of
the system and as for reference.
For volume production you might request to test and qualify other types of RAM. In order to qualify RAM it is
recommend configuring 3 systems running RAM Stress Test program in heat chamber at 60° C for a minimum of 24
hours.

3.7. On-board Graphics Subsystem
The SDML-WLU0 Series supports Intel® UHD Graphics technology for high quality graphics capabilities. All SDMLWLU0 Series versions support Intel® SDM-L compliant display with DP and / or HDMI 2.0 signal support via SDM
connector.

Display Max. Resolution (Px) at 60 Hz
DP 4096 x 2304
HDMI 2.0 4096 x 2160
3.8. Power Supply Voltage
In order to ensure safe operation of the module, the input power supply must monitor the supply voltage and shut
down if the supply is out of range -- refer to the actual power supply specification. Please note, in order to keep the
power consumption to a minimal level, modules do not implement a guaranteed minimum load. The SDML-WLU0
Series module must be powered through Intel® SDM compliant PCIe x8 edge connector from an Intel® SDM ready
display or power supply daughter card for DC 12 V and 3.3 VSB power supply.
The requirements to the supply voltages are as follows:
Table 7: Supply Voltages
Hot Plugging power supply is not supported. Hot plugging might damage the module.
Supply Min. Max. Note
+12 V 11.4 V 12.6 V Should be ±5 % tolerance
3.3 VSB 3.135 V 3.465 V Should be ±5 % tolerance
