Chapter 1 <Introduction>
1.1 <Product Overview>
LE-37H is 3.5 inch Motherboard which is design based on Intel® Celeron® Processor
N3350, and Intel® Pentium® Processor N4200 (Apollo Lake SoC), delivering outstanding
compute, graphical, and media performance while operating in an extended range of
thermal conditions. The SoC bases on the Silvermont microarchitecture, utilizing Intel’s
industry-leading 14nm process technology with 3-D Tri-Gate transistors, which deliver
significant improvements in computational performance and energy efficiency.
New features for Apollo Lake
The Intel® Celeron® Processor N3350, and Intel® Pentium® Processor N4200 have a
lower TDP 6W, it provides new HD Graphics to support triple display, 4K resolution,
maximum memory size is up to 8GB of DDR3L, and more enhanced security that is suitable
for a variety of intelligent systems the ideal choice.
All in One multimedia solution
The board provides high performance onboard graphics, 18/24-bit single/dual channel
LVDS interface, DisplayPort, HDMI, and High Definition Audio, to meet the very requirement
of the multimedia application.
Flexible Expansion Interface
The board provides one MiniPCIe and support mSATA.
Apollo Lake only support Windows10 64bit
So far Intel just support Windows 10 64bit. It may lose some drivers if you use other
Windows version.
