FCC and DOC Statement on Class B
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reason-
able protection against harmful interference when the equipment is operated in a residential
installation. This equipment generates, uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction manual, may cause harmful interference
to radio communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, the user is encour-
aged to try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and the receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver
is connected.
• Consult the dealer or an experienced radio TV technician for help.
Notice:
1. The changes or modifications not expressly approved by the party responsible for compli-
ance could void the user’s authority to operate the equipment.
2. Shielded interface cables must be used in order to comply with the emission limits.

Warranty
1. Warranty does not cover damages or failures that arised from misuse of the product, in-
ability to use the product, unauthorized replacement or alteration of components and prod-
uct specifications.
2. The warranty is void if the product has been subjected to physical abuse, improper instal-
lation, modification, accidents or unauthorized repair of the product.
3. Unless otherwise instructed in this user’s manual, the user may not, under any circum-
stances, attempt to perform service, adjustments or repairs on the product, whether in or
out of warranty. It must be returned to the purchase point, factory or authorized service
agency for all such work.
4. We will not be liable for any indirect, special, incidental or consequential damages to the

Static Electricity Precautions
It is quite easy to inadvertently damage your PC, system board, components or devices even
before installing them in your system unit. Static electrical discharge can damage computer
components without causing any signs of physical damage. You must take extra care in han-
dling them to ensure against electrostatic build-up.
1. To prevent electrostatic build-up, leave the system board in its anti-static bag until you are
ready to install it.
2. Wear an antistatic wrist strap.
3. Do all preparation work on a static-free surface.
4. Hold the device only by its edges. Be careful not to touch any of the components, contacts
or connections.
5. Avoid touching the pins or contacts on all modules and connectors. Hold modules or con-
nectors by their ends.
Safety Measures
To avoid damage to the system:
• Use the correct AC input voltage range.
To reduce the risk of electric shock:
• Unplug the power cord before removing the system chassis cover for installation or servic-
ing. After installation or servicing, cover the system chassis before plugging the power
cord.
Important:
Electrostatic discharge (ESD) can damage your processor, disk drive and other com-
ponents. Perform the upgrade instruction procedures described at an ESD worksta-
tion only. If such a station is not available, you can provide some ESD protection by
wearing an antistatic wrist strap and attaching it to a metal part of the system chas-
sis. If a wrist strap is unavailable, establish and maintain contact with the system
chassis throughout any procedures requiring ESD protection.

Features
• DDR3L
DDR3L SDRAM provides backward compatibility to DDR3 memory modules but can operate at
the same or at a lower power level.
• Storage
The board features SD card and eMMC memory for storing system firmware. And with the
i.MX6 Quad processor, an additional Serial ATA 2.0 port is provided for storing system and user
data.
• Gigabit LAN
The Ethernet LAN is built around the Atheros AR8033 Ethernet controller (10/100/1000Mbps).
• Power Failure Recovery
When power returns after an AC power failure, you may choose to either power on the system
manually or let the system power on automatically.
• USB
The system board supports the USB 2.0 to provide two USB host Type-A ports, one USB OTG
port and one internal pin header for two additional USB ports.
• CAN bus
The onboard CAN (Controller Area Network) connector complies with CAN Version 2.0B and
provides communication to CAN devices.

Important:
Electrostatic discharge (ESD) can damage your board, processor, disk drives, add-in
boards, and other components. Perform installation procedures at an ESD workstation
only. If such a station is not available, you can provide some ESD protection by wear-
ing an antistatic wrist strap and attaching it to a metal part of the system chassis. If
a wrist strap is unavailable, establish and maintain contact with the system chassis
throughout any procedures requiring ESD protection.
Important:
The Debug LED lights red until the operating system is being accessed. Power-off the
PC then unplug the power cord prior to installing any devices. Failure to do so will
cause severe damage to the motherboard and components.

JP1 is used to select the method of powering on the system. If you want the system to power
on whenever AC power comes in, set JP1 pins 4 and 6 to On. If you want to use the power
button, set pins 2 and 4 to On.
When using the JP1 “Power On” feature to power the system back on after a power failure
occurs, the system may not power on if the power lost is resumed within 5 seconds (power
flicker).
JP1 is also used to select the power supplied with the LCD panel.
Important:
Before powering-on the system, make sure that the power settings of JP1 match the
LCD panel’s specification. Selecting the incorrect voltage will seriously damage the
LCD panel.
