Chapter 2 Installation
is is a 3.5"SBC (5.8-in x 4-in x 1-in, 14.7 cm x 10.2 cm x 2.6cm) form factor motherboard.
Before you install the motherboard, study the conguration of your chassis to ensure that the
motherboard ts into it.
2.1 Screw Holes
Place screws into the holes to secure the motherboard to the chassis.
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 (e thermal solution of whole system needs to be designed additionally.)
Make sure to unplug the power cord before installing or removing the motherboard. Failure to
do so may cause physical injuries to you and damages to motherboard components.
Do not over-tighten the screws! Doing so may damage the motherboard.
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.

10
2.3 Installation of Memory Modules (SO-DIMM)
SBC-261J provides one 262-pin DDR5 (Double Data Rate 5) SO-DIMM slots, and supports
Single Channel Memory Technology.
Step 1. Align a SO-DIMM on the slot such that the notch on the SO-DIMM matches the
break on the slot.
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.
e 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 orien-
tation.

2.4 Expansion Slots
ere are two M.2 sockets on this motherboard.
M.2 sockets: 1 x M.2 (Key E, 2230) with PCIe x1, USB 2.0 and CNVi for Wireless
1 x M.2 (K ey M, 2242/2260/2280) with PCIe x1 or SATA3 and USB 2.0 for SSD

2.5 Jumpers Setup
The illustration shows how jumpers are 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
shows a 3-pin jumper whose pin1 and pin2 are
“Short” when jumper cap is placed on these 2
pins.
