Warning !
1. Battery
Batteries on board are consumables.
The life time of them are not guaranteed.
2. Fanless solution with HDD
The specifi cation & limitation of HDD should be considered carefully when
the fanless solution is implemented.
3. We will not give further notifi cation in case of changes of
product information and manual.
4. SATA interface does not support Hot SWAP function.
5. There might be a 20% inaccuracy of WDT at room temperature.
6. Please make sure the voltage specifi cation meets the requirement
of equipment before plugging in.
8. Caution! Please notice that the heat dissipation problem could cause the MB
system unstable. Please deal with heat dissipation properly when
buying single MB set.
9. Please avoid approaching the heat sink area to prevent users from
being scalded with fanless products.
12. It is important to install a system fan toward the CPU to decrease
the possibility of overheating / system hanging up issues,
or customer is suggested to have a fi ne cooling system to dissipate heat
from CPU.
11. DO NOT apply any other material which may reduce cooling
performance onto the thermal pad.
10. If users repair, modify or destroy any component of product unauthorizedly,
We will not take responsibility or provide warranty anymore.
7. There are two types of SSD, commercial grade and industrial grade, which
provide diff erent read/write speed performance, operation temperature and
life cycle. Please contact sales for further information before making orders.

Hardware Notice Guide
1. Before linking power supply with the motherboard, please attach DC-in adapter to
the motherboard fi rst. Then plug the adapter power to AC outlet.
Always shut down the computer normally before you move the system unit or
remove the power supply from the motherboard. Please unplug the DC-in adapter fi rst
and then unplug the adapter from the AC outlet.
Please refer photo 1 as standard procedures.
2. In case of using DIRECT DC-in (without adapter), please check the allowed range
for voltage & current of cables. And make sure you have the safety protection for
outer issues such as short / broken circuit, overvoltage, surge, lightning strike.
3. In case of using DC-out to an external device, please make sure its voltage and
current comply with the motherboard specifi cation.
4. The total power consumption is determined by various conditions
(CPU / motherboard type, device, application, etc.). Be cautious to the power cable
you use for the system, one with UL standard will be highly recommended.
5. It’s highly possible to burn out the CPU if you change / modify any parts of
the CPU cooler.
6. Please wear wrist strap and attach it to a metal part of the system unit
before handling a component. You can also touch an object which is
ground connected or attached with metal surface if you don't have wrist strap.
7. Please be careful to handle & don't touch the sharp-pointed components on
the bottom of PCBA.
8. Remove or change any components form the motherboard will VOID the warranty of
the motherboard.
9. Before you install / remove any components or even make any jumper setting
on the motherboard, please make sure to disconnect the power supply fi rst.
(follow the aforementioned instruction guide)
10. "POWERON after PWR-Fail" function must be used carefully as below:
When the DC power adaptor runs out of power, unplug it from the DC current;
Once power returns, plug it back after 5 seconds.
If there is a power outage, unplug it from the AC current, once power returns,
plug it back after 30 seconds. Otherwise it will cause system locked or made
a severe damage.
Remark 1:
Always insert / unplug the DC-in horizontally & directly to / from the motherboard.
DO NOT twist, it is designed to fi t snugly.
Moreover, erratic pull / push action might cause an unpredictable damage to the
component & system unit.

General Information
The 2I640DW is a 2.5" (110 x 98 mm) motherboard powered with Intel Atom® x6000E
series and Celeron® J (formerly Elkhart Lake) processor & off ered the ideal platform for
high performance applications. The ultra compact (110 x 98 mm) motherboard with wide
range 9~24V DC power input & embeds multiple Intel GbE LAN, USBs, COM Ports and
HDMI display interface that off er the ideal platforms for high performance applications in
Networking, Smart Automation, Machine Vision, In-vehicle, Industry 4.0 and any compact
high-performance Internet of Things (IoT) applications.
The 2I640DW supports high-speed data transfer interfaces such as PCIe gen3, USB 3.0,
and SATA 6 Gb/s (SATA III) for SATA-SSD interface M.2 B-Key device, with one-channel
DDR4 3200 MHz memory up to 32GB SODIMM slot and supports two serial ports RS232 /
RS485 / RS422 jumper free auto switch by BIOS. It supports 2 ports of USB 3.0, 3 ports of
USB 2.0. The expandable interfaces include 1 M.2 B-Key for PCIe x 2 or SATA-SSD (auto-
detection) and USB interface, and 1 M.2 B-Key PCIe x 2 and USB 3.0 / 2.0 interface.
The embedded motherboard 2I640DW is specially designed with Wide-Range Voltage DC
in (9~24V) for widely varying input voltage requirement. All wafer IO design off ers superb
performance and PC specifi cation in the industry using the specifi c housing. It supports
with three 10 / 100 / 1000 Mbps Ethernet for seamless broadband connectivity. With
Wake-On LAN function and the PXE function in BIOS, these are perfect control boards for
networking devices.
