Installation

This is a Mini-STX form factor (5.5″ x 5.8″) motherboard. Before you install the motherboard, study the configuration of your chassis to ensure that the motherboard fits into it. Make sure to unplug the power cord before installing or removing the motherboard. Failure to do so may cause physical injuries to you and damage to motherboard components.
Screw Holes
Place screws into the holes to secure the motherboard to the chassis. Do not over-tighten the screws! Doing so may damage the motherboard.

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

1. Unplug the power cord from the wall socket before touching any component.
2. To avoid damaging the motherboard components due to static electricity, NEVER place your motherboard directly on the carpet or the like. Also, remember to use a grounded wrist strap or touch a safety-ground object before you handle components.
3. Hold components by the edges and do not touch the ICs.
4. Whenever you uninstall any component, place it on a grounded antistatic pad or in the bag that comes with the component.

Before you install or remove any component, ensure that the power is switched off or the power cord is detached from the power supply. Failure to do so may cause severe damage to the motherboard, peripherals, and/or components.

Installation of Memory Modules (SO-DIMM)
This motherboard provides two 260-pin DDR4 (Double Data Rate 4) SO-DIMM slots.

1. It is not allowed to install a DDR, DDR2, or DDR3 memory module into a DDR4 slot; otherwise, this motherboard and SO-DIMM may be damaged.
2. Please make sure to disconnect the power supply before adding or removing SO-DIMMs or the system components.
3. The SO-DIMM only fits in one correct orientation. It will cause permanent damage to the motherboard and the SO-DIMM if you force the SO-DIMM into the slot at an incorrect orientation.

Installing a SO-DIMM

1. Align an SO-DIMM on the slot such that the notch on the SO-DIMM matches the break on the slot.
2. Firmly insert the SO-DIMM into the slot until the retaining clips at both ends fully snap back in place and the SO-DIMM is properly seated.

Expansion Slots
There are 3 M.2 sockets and 1 SIM socket on this motherboard.
SIM socket
1 x SIM socket connected to M.2 key B.
M.2 slots

• 1 x M.2 (M2_M1, Key M, 2242/2260/2280) with SATA3 and PCIe Gen4 x4 for SSD. (Shared with SATA3_0.)
• 1 x M.2 (M2_E1, Key E, 2230) with PCIe x1, USB 2.0 and CNVi for Wireless.
• 1 x M.2 (M2_B1, Key B, 3042/3052/2280) with PCIe x1 / USB 3.2 / USB2.0 and SIM for 4G/5G.

Jumpers Setup
The illustration shows how jumpers are set up. When the jumper cap is placed on pins, the jumper is “Short”. If no jumper cap is placed on pins, the jumper is “Open”. The illustration shows a 3-pin jumper whose pin1 and pin2 are “Short” when jumper cap is placed on these 2 pins.

Clear CMOS Jumper

(3-pin CLRMOS1) (see p.9, No. 24)

Note: CLRMOS1 allows you to clear the data in CMOS. To clear and reset the system parameters to the default setup, please turn off the computer and unplug the power cord from the system. After waiting for 15 seconds, use a jumper cap to short pin2 and pin3 on CLRMOS1 for 5 seconds. However, please do not clear the CMOS right after you update the BIOS. If you need to clear the CMOS when you just finish updating the BIOS, you must boot up the system first, and then shut it down before you do the clear-CMOS action. Please note that the date, time, and user default profile will be cleared only if the CMOS battery is removed.

Digital Input / Output Power Select (JGPIOPWR)

(3-pin JGPIO_PWR1)(see p.9 No. 19)

• 1-2: +12V
•  2-3: +5V

Panel Power Select (LCD_VCC)

• 1- 2: LVDD: +3V
• 2- 3: LVDD: +5V
• 4-5: LVDD: +12V

Backlight Power Select (LCD_BLT_VCC)

(5-pin BKT_PWR1) (see p.9 No. 6)Use this to set up the backlight power of the LVDS connector and the panel backlight power of BLT_PWM1.

• 1- 2: LCD_BLT_VCC: +5V
• 2- 3: LCD_BLT_VCC: +12V
• 4-5: LCD_BLT_VCC: DC_IN

Backlight Control Level (CON_LBKLT_CTL)

(3-pin BLT_PWM1) (see p.9, No. 10)

• 1- 2: eDP Level
• 2- 3: CH7511B Control

• 1-2: Pull-High
• 2-3: Pull-Low

BL1, BL2

****(2-pin BL1) Short:(see p.9, No. 3)

•  Open: Protect LCD_BLT_VCC
•  No Protect LCD_BLT_VCC

(2-pin BL2) Open: (see p.9, No. 3)

• Open: Protect LCD_VCC
• Short: No Protect LCD_VCC

ATX/AT Mode Jumper

(2-pin SIO_AT1)(see p.9, No. 26)

• Open : ATX Mode
•   Short : AT Mode

Chassis Intrusion Header

(2-pin CI1: see p.9, No. 27)This motherboard supports a CASE OPEN detection feature that detects if the chassis cover has been removed. This feature requires a chassis with a chassis intrusion detection design.

• Short : Active Case Open
• Open : Normal

Onboard Headers and Connectors

Onboard headers and connectors are NOT jumpers. Do NOT place jumper caps over these headers and connectors. Placing jumper caps over the headers and connectors will cause permanent damage to the motherboard!

SATA3 Connectors

(SATA3_0, SATA3_1: see p.9, No. 15)These two Serial ATA3 (SATA3) connectors support SATA data cables for internal storage devices. The current SATA3 interface allows up to 6.0 Gb/s data transfer rate. SATA3_0 is shared with M2_M1.

System Panel Header

(9-pin PANEL1)(see p.9 No. 14)This header accommodates several system front panel functions. Connect the power switch, reset switch, and system status indicator on the chassis to this header according to the pin assignments below. Note the positive and negative pins before connecting the cables.

PWRBTN (Power Switch)
Connect to the power switch on the chassis front panel. You may configure the way to turn off your system using the power switch.

RESET (Reset Switch)
Connect to the reset switch on the chassis front panel. Press the reset switch to restart the computer if the computer freezes and fails to perform a normal restart.

PLED (System Power LED)
Connect to the power status indicator on the chassis front panel. The LED is on when the system is operating. The LED keeps blinking when the system is in an S1 sleep state. The LED is off when the system is in an S3/S4 sleep state or powered off (S5).

HDLED (Hard Drive Activity LED)
Connect to the hard drive activity LED on the chassis front panel. The LED is on when the hard drive is reading or writing data. The front panel design may differ by chassis. A front panel module mainly consists of a power switch, reset switch, power LED, hard drive activity LED, speaker, etc. When connecting your chassis front panel module to this header, make sure the wire assignments and the pin assignments are matched correctly.

3W Audio AMP Output Wafer

(4-pin SPEAKER1) (see p.9 No. 7)

Front Panel Audio Header

(9-pin HD_AUDIO1) (see p.9 No. 9) This is an interface for front panel audio cable that allows convenient connection and control of audio devices.

1. High-definition audio supports Jack Sensing, but the panel wire on the chassis must support HDA to function correctly. Please follow the instructions in our manual and chassis manual to install your system.
2. If you use the AC’97 audio panel, please install it to the front panel audio header as below:
3.  Connect Mic_IN (MIC) to MIC2_L.
4. Connect Audio_R (RIN) to OUT2_R and Audio_L (LIN) to OUT2_L.
5. Connect Ground (GND) to Ground (GND).
6. MIC_RET and OUT_RET are for HD audio panels only. You don’t need to connect them to the AC’97 audio panel.
7. To activate the front mic. Go to the “FrontMic” Tab in the Realtek Control panel. Adjust “Recording Volume”.

SPDIF Header

(3-pin SPDIF1: see p.9, No. 8)

Chassis Fan Connector

(+12V) (4-pin CHA_FAN1) (see p.9 No. 11)Please connect the chassis fan cable to the connector and match the black wire to the ground pin. Though this motherboard provides 4-Pin chassis fan (Quiet Fan) support, the 3-Pin chassis fan still can work successfully even without the fan speed control function. If you plan to connect the 3-Pin chassis fan to the chassis fan connector on this motherboard, please connect it to Pin 1-3.

USB 2.0 Connector

(9-pin USB2_6_7)(see p.9 No. 25)There is one USB 2.0 connector on this motherboard. This USB 2.0 connector can support two USB ports.

LVDS Connector
