Chapter 2 Installation
is is a Mini-ITX (6.7-in x 6.7-in x 1.5-in, 17.0 cm x 17.0 cm x 3.8 cm) form factor mother-
board. 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
IMB-1235 provides two 260-pin DDR4 (Double Data Rate 4) SO-DIMM slots, and supports
Dual 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.
1. 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 incor-
rect orientation.
2. Please do not intermix dierent voltage SO-DIMMs on this motherboard.

IMB-1235
2.4 Expansion Slots
ere are 3 M.2 sockets and 1 SIM socket on this motherboard.
M.2 sockets: 1 x M.2 (Key B, 3042/3052) with PCIe Gen3 x1, USB 3.2, USB 2.0 and SIM for
4G/5G
1 x M.2 (Key E, 2230) with PCIe Gen3 x1, USB 2.0 and CNVi for Wireless
