1/ Introduction
This manual describes the Mini ITX Skylake S/C236 board. This board will also be denoted mITX-SKL-S-C236 within
this Users Guide.
The use of this Users Guide implies a basic knowledge of PC hard- and software. This manual is focussed on
describing the mITX-SKL-S-C236 board’s special features and is not intended to be a standard PC 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 done automatically or manually by the user via the BIOS setup
menus.
Latest revision of this manual, datasheet, thermal simulations, BIOS, drivers, BSP’s (Board Support Packages) can be
downloaded from Kontron Web Page.

2/ Description
The mainboard mITX-SKL-S-C236 is based on the Skylake processor family. It uses the Intel Platform Controller Hub
(PCH) C236. This powerful hardware with efficient graphic and network capabilities offers a broad range of
application areas. The processor, graphics and memory controller is built on 22 nm die.
Main characteristics are:
Support Skylake Family Processors LGA1151 CPU Socket (37.5 mm x 37.5 mm)
Range from 35 to 65W TDP
Intel®SKL C236 PCH chipset
2x ECC/NON ECC SODIMM Memory Architecture
Max. three independent displays by Display Port (3x DP) or LVDS
Three Gigabit Ethernet ports
ECC memory optional
Four SATA 3.0 Ports
M.2 and PCIe minicard
Built with these functions, mITX-SKL-S-C236 motherboard is ideal for ATM, automation, Kiosk applications, medical
equipment, industrial automation, financial automation, process control, semiconductor equipment, and network
security markets.
2.1. Product Variants
The mITX-SKL-S-C236 has two product variants depending on the display requirements:

mITX-SKL-S-C236 with 2x DP + 1x LVDS (part number: 810685-4500)

mITX-SKL-S-C236 with 3x DP (part number: 810686-4500)

3/ Installation procedure
3.1. Packing Check List
The mITX-SKL-S-C236 package includes the following basic items accompany with this manual.
One main board
One IO shield
If any of these items is damaged or missed, please contact your vendor and save all packing materials for future
replacement and maintenance.
The above packing list is for standard single box packing only.
3.2. 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 MΩto 10 MΩ)
•Transport and store the board in its antistatic bag
•Handle the board at an approved ESD workstation
•Handle the board only by the edges
To get the board running follow these steps. If the board shipped from Kontron has already components like RAM
and CPU cooler mounted, then relevant steps below can be skipped.
Only connect to a power supply delivering the specified input rating and complying with the
requirements of Safety Extra Low Voltage (SELV) and Limited Power Source (L.P.S.) of IEC
60950-1 and the Energy sources (ES1) of IEC 62368-1.
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 +12V single supply
only. Alternatively use a standard ATX PSU with suitable cable kit and PS_ON# active.
2.
Insert the DDR4 SO-DIMM 260 pin module(s)
Be careful to push it in the slot(s) before locking the tabs. For a list of approved SO-DIMMs contact your
Distributor or FAE. See also chapter “System Memory Support”. Use SO-DIMM with the same memory density in
both sockets!
3.
Processor installation
Install the processor in the processor connector. Follow the steps in the delivered manual from the processor
manufacturer.
4.
Cooler Installation
You can connect the cooler fan electrically to the FANCPU connector.

mITX-SKL-S-C236 Doc. Rev. 1.6
www.kontron.com // 13
5.
Connecting Interface
s
Insert all external cables for hard disk, keyboard etc. A monitor must be connected in order to change BIOS
settings.
6.
Connect and turn on PSU
Connect PSU to the board by the External Power of ATXPWR (20 poles power plug) and Internal Power of ATX4p
(4 poles power plug) to the I/O Power jack.
7.
Power Button
If the board does not start by itself when switching on the ATX/DC PSU AC mains, then follow these instructions
to start the board. I
8.
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 > 10 sec (without power connected).
9. 156BMounting the board in chassis
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.
When mounting the board to chassis etc. please notice that the board contains components
on both sides of the PCB which can easily be damaged if board is handled without
reasonable care. A damaged component can result in malfunction or no function at all.
Vibration may cause damage to boards
When setting up boards within a system, steps must be taken to reduce the level of
vibration within the system. It is the user’s responsibility to ensure that boards can function
properly in their system.
3.3. Requirements IEC60950-1
Take care when designing chassis interface connectors in order to fulfil the IEC60950-1 standard.
Users of mITX-SKL-S-C236 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 air flow considerations.

The motherboard must be powered by a CSA or UL approved power supply that limits the maximum input
current to 10 A via external barrel-type 12-24 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 IEC60950-1.

5/ Jumpers and Connectors
5.1. Hardware Configuration Setting
This chapter gives the definitions and shows the positions of jumpers, headers and connectors. All of the
configuration jumpers on the board are in the proper position. The default settings shipped from factory are marked
with an asterisk (*).
In general, jumpers on the board are used to select options for certain features. Some of the jumpers are designed to
be user-configurable, allowing for system enhancement. The others are for testing purpose only and should not be
altered. To select any option, cover the jumper cap over (SHORT) or remove (NC) it from the jumper pins according to
the following instructions. Here, NC stands for “Not Connect”.
