ESD Warning
Electronic components and circuits are sensitive to
ElectroStatic Discharge (ESD). When handling any
circuit board assemblies including Connect Tech
COM Express carrier assemblies, it is recommended
that ESD safety precautions be observed. ESD safe
best practices include, but are not limited to:
•Leaving circuit boards in their antistatic
packaging until they are ready to be installed.
•Using a grounded wrist strap when handling
circuit boards, at a minimum you should touch a
grounded metal object to dissipate any static
charge that may be present on you.
•Only handling circuit boards in ESD safe areas,
which may include ESD floor and table mats,
wrist strap stations and ESD safe lab coats.
•Avoiding handling circuit boards in carpeted
areas.
•Try to handle the board by the edges, avoiding
contact with components.

INTRODUCTION
Connect Tech’s SMARC 2.0 carrier is an extremely small SMARC carrier board ideal for low power IoT
applications as users can take advantage of the integrated on-board wireless capabilities found on the
SMARC 2.0 modules. The carrier has USB 3.0, USB 2.0, 2x MIPI CSI-2 camera interfaces, HDMI outputs,
microSD, and expansion via two mini PCIe Full size slots.
Connect Tech’s SMARC 2.0 carrier board supports the latest generation Apollo Lake x86 low-powered
processors and exposes next-generation interconnect (USB 3.0, DDI, MIPI-CSI-2).
SMARC 2.0 supports an extended temperature range of -40°C to +85°C and offers a very small footprint;
ideal for mobile or stationary applications.

HDMI0 DDC Level Translation Select Jumper
Some SMARC module manufacturers do not use 1.8V signal levels for the HDMI DDC interface, for the
best and most reliable performance it is required the correct voltage level is used.
Note that prolonged use at the incorrect voltage level may cause damage. If you are unsure what logic
level your SMARC module uses please contact the manufacturer or [e-mail].
Customers using the Congatec conga-SA5 will need to set this jumper to 3.3V (position 1-2).
