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.

1/ Introduction
This manual describes the Smart Mobility ARChitecture SMARC Eval-Carrier-2 board. This document describes the
electronic, mechanical and thermal design of the SMARC evaluation carrierboard. It is designed for the testing of
SMARC-sXAL (2), SMARC_SMX7 and other SMARC 2.0 modules. The board will be equipped with DP++ connector,
HDMI connector, LVDS connector, two full-size or half-size mPCIe card slot (PCIe + USB 2.0), two PCIe x1 slot and
full-size mSATA slot to easily use and test additional cards.
The use of this Users Guide implies a basic knowledge of PC hard- and software. This manual is focussed on
describing the 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, BIOS, drivers and BSP’s (Board Support Packages) can be
downloaded from Kontron Web Page.

3.1. Packing Check List
The package includes the following basic items accompany with this manual.
One board
If this item is damaged or missed, please contact your vendor and save all packing materials for future replacement
and maintenance.
Note: The above packing list is for standard single box packing only.
3.2. Requirements IEC60950-1
Take care when designing chassis interface connectors in order to fulfil the IEC60950-1 standard.
Users of board 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.
For interfaces having a power pin such as external power or fan, ensure that the connectors and wires are suitably
rated. All connections from or to the product shall be with Safety Extra Low Voltage (SELV) circuits only.
Wires have suitable rating to withstand the maximum available power.
The enclosure of the peripheral device fulfills 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”.

Module power selection: Either internal power
via J53 (5 V supply), or external via J54 (3 to
5.25 V supply).
ATTENTION: J54 powers the module ONLY!
Carrier still needs to be powered via 12V,
through J53.
