3.5-SBC-APL – Rev. 0.1
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.

2/ Installation Procedures
2.1. Installing the Board
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 (OK: 1 MΩ to 10 MΩ)
•Transport and store the board in an antistatic bag
•Handle the board only at an approved ESD workstation
•Handle the board only by the edges
To get the board running follow the steps listed below. If the board shipped by KONTRON already has components
such as a RAM and CPU cooler mounted, then skip the relevant step(s).
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. Otherwise
components (RAM, LAN cards etc.) might get damaged. Make sure to use a standard ATX
PSU with a suitable cable kit and PS_ON# active.
2.
Insert the memory module(s)
Be careful to push the memory module in the slot(s) before locking the tabs.
3.
Cooler Installation
The 3.5-SBC-APL comes with a pre-installed cooler.
4.
Connecting Interface
s
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 4-pin connector.
6.
BIOS Setup
Enter the BIOS setup by pressing the <DEL> key during boot up. Enter “Exit Menu” and Load Setup Defaults. For
BIOS setup information, see Chapter 8/ in this User Guide.
To clear all BIOS settings, including Password protection, activate “Load Default BIOS
Settings” Clear CMOS Jumper for >
10 sec (without power connected).
7.
Mounting the board in chassis
When mounting the board to chassis etc. please note that the board contains
components on both sides of the PCB that can easily be damaged if board is handled

3.5-SBC-APL – Rev. 0.1
www.kontron.com // 13
without reasonable care. A damaged component can result in malfunction or no
function at all.
When fixing the Motherboard on a chassis it is recommended to use screws with integrated washer and a
diameter of >7 mm. Do not use washers with teeth, as they can damage the PCB and cause short circuits.
2.2. Chassis Safety Standards
Take care when designing chassis interface connectors in order to fulfil the IEC60950-1 standard. 3.5-SBC-APL users
must evaluate the end product to ensure compliance the requirements of the IEC60950-1 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 airflow considerations.
The motherboard must be powered by a CSA or UL approved power supply that limits the maximum input current
to 15 A via internal square ATX +12 V 4-pin 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 IEC60950-1.
Danger of explosion if the lithium battery is incorrectly replaced.
Replace only with the same or equivalent type recommended by the manufacturer
Dispose of used batteries according to the manufacturer’s instructions

4.4.1. Processor Cooling
The 3.5-SBC-APL supports a combined cooling method with passive or active cooler to provide sufficient cooling to
the processor and to remove the effects of TDP (Thermal Design Power). The level of sufficient cooling depends on
the worst-case maximum ambient operating temperature and the actual worst-case load of processor. The chipset is
cooled via passive cooling.

4.5. System Memory Support
The 3.5-SBC-APL has 1 GB of soldered down system memory and supports one DDR3L SO-DIMM socket. The sockets
support the following memory features:
DDR3L SO-DIMM 1.35 V (non ECC)
1x SO-DIMM DDR3L socket
Maximum support memory up to 8 GB
Memory controller speeds of 1867 MHz
The installed DDR 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.
4.6. Graphics
The 3.5-SBS-APL features on-board Intel® HD Graphics (Gen9LP) and supports three display pipes:
DisplayPort (DP)
HDMI
LVDS

4.7. Power Consumption
In order to ensure safe operation of the board, 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. In order to keep the power
consumption to a minimal level, boards do not implement a guaranteed minimum load. In some cases, this can lead to
compatibility problems with ATX power supplies that require a minimum load to stay in regulation.
The 3.5-SBC-APL is powered by either a single 12 V DC Power Supply or optionally through an internal ATX 4-pin
power connector using a standard ATX power supply.
Hot Plugging with the power supply is not supported. Hot plugging might damage the board.
ATX+12 V supply: ATX+12V 4-pin connector must be used in according to the ATX12V PSU
standard.
