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) sAMX7 (SMX7) board. The Advanced RISC Machines
(ARM) based module is equipped with a NXP i.MX7 processor. The single or dual core SoC take advantage of the
optimized power consumption and performance ratio.
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.

2/ Description
The SMARC-sAMX7 is a SMARC half-size module using the NXPs i.MX7 processor with either single or dual core
ARM. It is designed on the latest SMARC 2.0 specification. The SMARC-sAMX7 is a highly integrated, embedded
computer board.
Figure 1: Half-size Card with SMARC interface
2.1. SMARC™ Computer-on-Modules
The SMARC™ standard was developed especially for new modules with ARM- and SoC-processors. Boards with this
interfaces are characterized by the extremely flat form factor. The SMARC or MXM 3.0 connector comes with 314
pins and a construction height of just 4.3 millimeters. The connector is also available in a shock- and vibration-
resistant version for rough environmental conditions.
Furthermore, the standard integrates dedicated interfaces for the latest ARM, x86 and SoC processors like LVDS,
24-bit RGB and HDMI support. In addition, dedicated camera interfaces are being incorporated into a COM standard.
OEMs profit from minimized design effort and low Bill of Material (BoM) costs. SMARC™ defines two different
module sizes in order to offer a high level of flexibility regarding different mechanical requirements.
