Chapter 1 <Introduction>
1.1 <Product Overview>
LV-6715 is a Mini-ITX Motherboard which supports Alder Lake/12th Gen Processors,
integrated DDR5 memory, Realtek High Definition Audio, Intel Gigabit LAN, USB3.2 Gen2,
SATA3 with AHCI function for a system.
New feature for Alder Lake
Alder Lake/12th Gen Processors are based on the 7nm SuperFin process, and offer
long-life availability. i7-12800HE have Intel® Iris® Xe Graphics up to 96 EUs.
All in One multimedia solution
The board provides one MiniPCIe slot (support mSATA), one M.2 2230 slot, two M.2 2280
slot (PCIe Gen4), and one PCIe x16 slot (PCIe Gen4 X8).
Alder Lake support Windows10 version 21H2 64bit and Linux 5.18
Intel recommends using Windows 10 version 21H2 64bit. It may lose some drivers if you
use other Windows version.
