Product Introduction

Chapter 2: Product Introduction

2.1 Before you proceed

Take note of the following precautions before you install motherboard components or change any motherboard settings.

NOTE: The diagrams in this chapter are for reference only. The motherboard layout may vary with models.

IMPORTANT! Components shown in this section may require additional purchase. Refer to Package contents section for more information about the contents of your Single Board Computer package.

WARNING!

• Unplug the power cord from the wall socket before touching any component.

• Before handling components, use a grounded wrist strap or touch a safely grounded object or a metal object, such as the power supply case, to avoid damaging them due to static electricity.

• Hold components by the edges to avoid touching the ICs on them.

• Whenever you uninstall any component, place it on a grounded antistatic pad or in the bag that came with the component.

• Before you install or remove any component, ensure that the ATX power supply 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, or components.

2.3 System memory

The motherboard comes with a Small Outline Dual Inline Memory Module (SODIMM) slot designed for DDR4 (Double Data Rate 4) memory modules.

Single Board Computer

2.4 Onboard jumpers

1. Clear RTC RAM jumper

The Clear RTC RAM jumper allows you to clear the Real Time Clock (RTC) RAM in the CMOS, which contains the date, time, system passwords, and system setup parameters.

To erase the RTC RAM:

1. Turn OFF the computer and unplug the power cord.

2. Short-circuit pin 1-2 with a metal object or jumper cap for about 5-10 seconds.

3. Plug the power cord and turn ON the computer.

4. Hold down the <Del> key during the boot process and enter BIOS setup to re-enter data.

WARNING! DO NOT remove the jumper cap from its default position

except when clearing the RTC RAM. Removing the jumper cap will cause system boot failure!

NOTE: If the steps above do not help, remove the onboard button cell battery and move the jumper again to clear the CMOS RTC RAM data. After clearing the CMOS, reinstall the button cell battery.

Single Board Computer

2. LVDS Panel Power Selection jumper (on selected models)

The LVDS Panel Power jumper allows you to select the voltage for the LVDS panel.

3. Back Light Power Selection jumper (on selected models)

The Back Light Power Selection jumper allow you to select the voltage for the LVDS back light module.

Single Board Computer

4. Back Light Power Enable jumper (on selected models)

The Back Light Power Enable jumper allows you to congure the power setting for the panel.

5. HW WDT Enable jumper

A watchdog timer is an electronic timer that is used to detect and recover from computer malfunctions. The HW WDT (watchdog timer) Enable jumper allows the HW watchdog resets the system automatically even when the system crashes.

NOTE: The default setting for this jumper is set to HW WDT enabled with a jumper cap attached.

Single Board Computer

6. AT/ATX Mode Conguration jumper

The AT/ATX Mode Conguration jumper allows you to switch between AT or ATX modes. The default setting for this jumper is set to ATX mode with a jumper cap attached, to switch to AT mode, remove the jumper cap.

7. Mini PCIe/mSATA conguration jumper

The Mini PCIe/mSATA conguration jumper allows you to select between Mini PCIe mode or mSATA mode. Set to pins 1-2 for mSATA mode, or set to pins 2-3 for Mini PCIe mode.

Single Board Computer

2.5 Internal connectors

1. SATA 6Gb/s & SATA Power connector

The SATA 6Gb/s and SATA Power connectors allow you to connect SATA devices such as optical disc drives and hard disk drives via a SATA cable and power cable.

Connector type

NOTE: Ensure to use the bundled cable when connecting a storage

device to this connector.

Single Board Computer

Wafer HD 4P, 2.0mm pitch

2. Mini PCIe/mSATA slot

The Mini PCIe/mSATA slot allows you to install a Mini PCIe or mSATA peripheral device.

NOTE:

• The Mini PCIe / mSATA peripheral device is purchased separately.

• The mSATA shares the same slot with a full-length Mini PCIe.

Single Board Computer

3. Micro SD Card slot

The Micro SD Card slot allows you to install a Micro SD card.

NOTE: The Micro SD card is purchased separately.

4. M.2 slot

The M.2 slot allows you to install 2242 M.2 devices such as 2242 M.2 SSD modules.
