1.1 Introduction
Figure 1-1: KINO-DH420
The KINO-DH420 is a Mini-ITX motherboard. It accepts a Socket LGA1200 Intel® Core™
i7/i5/i3, Pentium® or Celeron® processor and supports two 260-pin 2933 MHz dual-
channel DDR4 SDRAM unbuffered SO-DIMM supporting up to 64GB.
The KINO-DH420 provides three 2.5 GbE interfaces through the Intel® I225V /I225LM
PCIe GbE controllers. The integrated Intel® H420E chipset supports two SATA 6Gb/s
drives, one M.2 (3042/3052/2242/2280) B key slot supporting PCIe x2 and USB 2.0 signal
and one M.2 2230 A-key slot supporting PCIe x1 and USB 2.0 signals. In addition, the
KINO-DH420 includes one HDMI port and one DP port for dual independent display.
Expansion and I/O include one PCIe x16 slot, four USB 3.2 Gen1 on the rear panel, two
USB 2.0 ports on the rear I/O and two USB 2.0 by pin headers, three RS-232 ports and
one RS-422/485 port. High Definition Audio (HDA) support ensures HDA devices can be
easily implemented on the KINO-DH420.
