Product Warranty (2 years)
Advantech warrants to you, the original purchaser, that each of its products will be
free from defects in materials and workmanship for two years from the date of pur-
chase.
This warranty does not apply to any products which have been repaired or altered by
persons other than repair personnel authorized by Advantech, or which have been
subject to misuse, abuse, accident, or improper installation. Advantech assumes no
liability under the terms of this warranty as a consequence of such events.
Because of Advantech’s high quality-control standards and rigorous testing, most of
our customers never need to use our repair service. If an Advantech product is defec-
tive, it will be repaired or replaced at no charge during the warranty period. For out-
of-warranty repairs, you will be billed according to the cost of replacement materials,
service time and freight. Please consult your dealer for more details.
If you think you have a defective product, follow these steps:
1. Collect all the information about the problem encountered. (For example, CPU
speed, Advantech products used, other hardware and software used, etc.) Note
anything abnormal and list any on screen messages you get when the problem
occurs.
2. Call your dealer and describe the problem. Please have your manual, product,
and any helpful information readily available.
3. If your product is diagnosed as defective, obtain an return merchandise authori-
zation (RMA) number from your dealer. This allows us to process your return
more quickly.
4. Carefully pack the defective product, a fully-completed Repair and Replacement
Order Card and a photocopy proof of purchase date (such as your sales receipt)
in a shippable container. A product returned without proof of the purchase date
is not eligible for warranty service.
5. Write the RMA number visibly on the outside of the package and ship it prepaid
to your dealer.

to avoid damage by transient over-voltage.
12. Never pour any liquid into an opening. This may cause fire or electrical shock.
13. Never open the equipment. For safety reasons, the equipment should be
opened only by qualified service personnel.
14. If one of the following situations arises, get the equipment checked by service
personnel:
The power cord or plug is damaged
Liquid has penetrated into the equipment
The equipment has been exposed to moisture
The equipment does not work well, or you cannot get it to work according to

Safety Precaution - Static Electricity
Follow these simple precautions to protect yourself from harm and the products from
damage.
To avoid electrical shock, always disconnect the power from your PC chassis
before you work on it. Don't touch any components on the CPU card or other
cards while the PC is on.
Disconnect power before making any configuration changes. The sudden rush
of power as you connect a jumper or install a card may damage sensitive elec-
tronic components.

1.1 Introduction
Advantech ROM-5620 SMARC2.0/2.1 Computer-on-Module (COM) is powered by
NXP i.MX 8X SoC which features 2 ~ 4 Arm Cortex-A35 cores for applications in the
automotive and industrial market. ROM-5620 has one Cortex-M4F core for real-time
processing, and one Tensilica Hi-Fi 4 DSP for efficient audio and voice processing. A
Vivante GC7000 Lite, 4K H.265 capable decoder, and dual 1080P60 display control-
lers enable excellent graphics processing performance. ROM-5620 is paired with
Advantech’s ROM-DB5901 Evaluation Carrier Board for faster end user peripheral
integration and decreased time-to-market. Reference schematics, layout checklists,
and other documentation necessary for carrier board development are provided. This
package also includes open-sourced Linux BSP, test utilities, hardware design utili-
ties, and reference drivers. ROM-5620 is an excellent choice for diverse industrial
automation, medical, Human-machine-Interface, and portable applications.
