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 prod
uct, 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 user guide describes the 25,5mmx25,5mm SoM form factor module – SL iMX6UL/ULL. The Advanced RISC
Machines (ARM) based module is equipped with a NXP i.MX6UL/ULL processor. The single core SoC takes advantage
of the optimized power consumption and performance ratio.
The use of this user guide implies a basic knowledge of PC hardware and software. This user guide is focused 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, before switching on the power.
Latest revision of this user guide, datasheet, and BSPs (Board Support Packages) can be downloaded from Kontron
Electronics Web Page.
