Chapter 2: Installation
This is a 3.5” SBC (5.8-in x 4.0-in) form factor (148 x 102 mm) motherboard. Before
you install the motherboard, study the conguration of your chassis to ensure that
the motherboard ts into it.
motherboard. Failure to do so may cause physical injuries to you and
damages to motherboard components.
Make sure to unplug the power cord before installing or removing the
2.1 Screw Holes
Place screws into the holes to secure the motherboard to the chassis.
Do not over-tighten the screws! Doing so may damage the motherboard.
2.2 Pre-installation Precautions
Take note of the following precautions before you install motherboard components
or change any motherboard settings.
1. Unplug the power cord from the wall socket before touching any component.
2. To avoid damaging the motherboard components due to static electricity,
NEVER place your motherboard directly on the carpet or the like. Also
remember to use a grounded wrist strap or touch a safety grounded object
before you handle components.
3. Hold components by the edges and do not touch the ICs.
4. Whenever you uninstall any component, place it on a grounded antistatic pad or
in the bag that comes with the component.
5. Heatsink (The thermal solution of whole system needs to be designed
additionally.)
Before you install or remove any component, ensure that the power is
switched o or the power cord is detached from the power supply.
Failure to do so may cause severe damage to the motherboard, peripherals,
and/or components.

2.3 Installation of Memory Modules (SO-DIMM)
SBC-211
supports single channel DDR3L SDRAM only.
Step 1. Align a SO-DIMM on the slot such that the notch on the SO-DIMM
matches the break on the slot.
The SO-DIMM only ts in one correct orientation. It will cause permanent damage to
the motherboard and the SO-DIMM if you force the SO-DIMM into the slot at
incorrect orientation.
provides one 204-pin DDR3 (Double Data Rate 3) SO-DIMM slot, which
Step 2. Firmly insert the SO-DIMM into the slot until the retaining clips at both
ends fully snap back in place and the SO-DIMM is properly seated.

2.4 Expansion Slots (mini-PCIe and mini-PCIe/mini-SATA
Slots)
There is 1 mini-PCIe slot and 1 mini-PCIe/mini-SATA slot on this motherboard.
mini-PCIe slot:
MINI_PCIE1 (mini-PCIe slot; half size) is used for PCI Express mini
cards.
mini-PCIe/mini-SATA slot:
MINI_PCIE2 (mini-PCIe/mini-SATA slot; full size) is used for PCI Ex-
press mini cards or mSATA cards.
Installing an expansion card
Step 1. Before installing the expansion card, please make sure that the power
supply is switched o or the power cord is unplugged. Please read the
documentation of the expansion card and make necessary hardware
settings for the card before you start the installation.
Step 2. Remove the system unit cover (if your motherboard is already installed
in a chassis).
Step 3. Remove the bracket facing the slot that you intend to use. Keep the
screws for later use.
Step 4. Align the card connector with the slot and press rmly until the card is
completely seated on the slot.
Step 5. Fasten the card to the chassis with screws.
Step 6. Replace the system cover.

2.5 Jumpers Setup
The i llust rat io n shows h ow jum pers a re
setup. When the jumper cap is placed on
pins, the jumper is “Short”. If no jumper cap
is placed on pins, the jumper is “Open”. The
illustration show s a 3-pin jum pe r w hose
pin1 and pin2 are “Short” when jumper cap
is placed on these 2 pins.
Clear CMOS Jumper
(CLRCMOS1)
(see p.8, No. 14)
Clear CMOSDefault
Note: CLRCMOS1 allows you to clear the data in CMOS. To clear and reset the
system parameters to default setup, please turn o the computer and unplug
the power cord from the power supply. After waiting for 15 seconds, use a
jumper cap to short pin2 and pin3 on CLRCMOS1 for 5 seconds. However,
please do not clear the CMOS right after you update the BIOS. If you need
to clear the CMOS when you just nish updating the BIOS, you must boot up
the system rst, and then shut it down before you do the clear-CMOS action.
Please be noted that the password, date, time, user default prole and MAC
address will be cleared only if the CMOS battery is removed.

2.6 Onboard Headers and Connectors
Onboard headers and connectors are NOT jumpers. Do NOT place
jumper caps over these headers and connectors. Placing jumper caps
over the headers and connectors will cause permanent damage of the
motherboard!
SATA2 Connectors These two Serial ATA2

Connect the power switch, reset switch and system status indicator on the
chassis to this header according to the pin assignments below. Note the
positive and negative pins before connecting the cables.
PWRBTN (Power Switch):
Connect to the power switch on the chassis front panel. You may congure
the way to turn o your system using the power switch.
RESET (Reset Switch):
Connect to the reset switch on the chassis front panel. Press the reset
switch to restart the computer if the computer freezes and fails to perform a
normal restart.
PLED (System Power LED):
Connect to the power status indicator on the chassis front panel. The LED
is on when the system is operating. The LED keeps blinking when the sys-
tem is in S1 sleep state. The LED is o when the system is in S3/S4 sleep
state or powered o (S5).

HDLED (Hard Drive Activity LED):
Connect to the hard drive activity LED on the chassis front panel. The LED
is on when the hard drive is reading or writing data.
The front panel design may dier by chassis. A front panel module mainly
consists of power switch, reset switch, power LED, hard drive activity LED,
speaker and etc. When connecting your chassis front panel module to this
header, make sure the wire assignments and the pin assign-ments are
matched correctly.
