ESD Precautions
Computer boards have integrated circuits sensitive to static electricity. To prevent chipsets
from electrostatic discharge damage, please observe the following precautions:
Do not remove modules or integrated circuits from their anti-static packaging until you are
ready to install them.
Before holding the module or any integrated circuit, touch an unpainted portion of the
system unit chassis for a few seconds. Doing so will help discharge static electricity from
your body.
When handling modules and components, wear a wrist-grounding strap, available from
most electronic component stores.

Introduction 1
Chapter 1
Introduction
The SDM500L is a new Intel®Smart Display Module (SDM-L) supporting the Intel® Core™
Whiskey Lake U processor. It delivers outstanding system performance and supports a diverse
range of multiple I/Os such as one Gigabyte Ethernet port, four USB 3.0 ports and one HDMI.
The SDM500L measures only 100 x 175mm and delivers 4K output with streaming content
through the SDM edge connector.
The SDM500L reserves two SO-DIMM slots, three types of M.2 sockets, plus one standard
PCIex8 (through the SDM edge connector). It also features built-in I/O interfaces including
USB 3.0, HDMI 1.4, DisplayPort 1.2, Serial TX/RX and I2C. In addition, for maximum
integration flexibility, the SDM500L can be built in or externally plugged into a display, which
allows this cost-effective smart display module to fit into even the sleekest all-in-one designs.
1.1 Features
Intel® Core™ Whiskey Lake U processor
Two SO-DIMM memory slots supporting memory capacity up to 32GB
One M.2 E Key 2230 for WiFi/BT, One M.2 B Key and One M.2 M key for storage options

2.3 Jumper Settings
A jumper is a small component consisting of a set of jumper pins with a jumper clip. Place a
jumper clip on two jumper pins to close; remove a jumper clip from two jumper pins to open.
The following illustration shows how to set up a jumper.
Properly configure jumper settings on the SDM300S to meet your application purpose. Below
you can find a summary table of jumpers and their default onboard settings.
Note
Once the default jumper setting needs to be changed, please do it under power-off
condition.

2.3.1 Clear CMOS (JP1)
To restore BIOS optimal defaults, put the jumper clip on pin 2-3 for a few seconds then
move it back to pin 1-2.
2.3.2 Auto Power on (JP2)
If JP2 is enabled for power input, the system will be automatically power on without the
need to press the soft power button. If JP1 is disabled for power input, it is necessary to
manually press the soft power button to power on the system.
