1 Introduction
This manual describes the mITX-E38 boards made by KONTRON Technology A/S. The boards will also be
denoted E38.
The E38 boards are based on Intel Atom E38xx SOC (System On Chip) and will be available in three versions
having 1, 2 or 4 cores. The differences between the three types of boards are listed in this table:
Feature mITX-E3815 mITX-E3826 mITX-E3845
Bay Trail SOC E3815 (1 core) E3826 (2cores) E3845 (4 cores)
Core speed 1,46GHz 1,46GHz 1,91GHz
Total Design Power 5W 7W 10W
Integrated cooler Passive Passive Active
Graphics 2x DP 2x DP DP + LVDS
Onboard eMMC - - 16GB TLC NAND
SD Card slot - Yes Yes
TPM - - Yes
COM ports 2x RS232 6x RS232 6x RS232
USB
Use of this Users Guide implies a basic knowledge of PC-AT hard- and software. This manual is focused on
describing the E38 board’s special features and is not intended to be a standard PC-AT textbook.
New users are recommended to study the short installation procedure stated in the following chapter
before switching-on the power.
All configuration and setup of the CPU board is either done automatically or manually by the user via the
BIOS setup menus. Only exceptions are the “Clear CMOS” Jumper and the “Always On” jumper.
Latest revision of this manual, datasheet, BIOS, drivers, BSP’s (Board Support Packages), Mechanical
drawings (2D and 3D) can be downloaded from here: http://www.kontron.com/products/boards-and-

mITX-E38 Users Guide
Warning: Turn off PSU (Power Supply Unit) completely (no mains power connected to the PSU) or
!
Note: To clear all BIOS settings, including Password protection, activate “Load Default BIOS Settings”
2 Installation Procedure
Installing the Board 2.1
To get the board running follow these steps. If the board shipped from KONTRON has already components
like RAM and CPU cooler mounted, then relevant steps below can be skipped.
1. Turn off the PSU (Power Supply Unit)
2. Insert the DDR3L SODIMM module
For a list of approved DDR3 DIMMs contact your Distributor or FAE. See also chapter “System Memory
Support”.
3. Cooler Installation
Normally the cooler is premounted, but in case not, then make sure the heat paste etc. on the cooler is
intact and cover the full area of the SOC. Connect Cooler Fan electrically to the FAN_CPU connector.
4. Connecting Interfaces
Insert all external cables for hard disk, keyboard etc. A monitor must be connected in order to change
BIOS settings.
5. Connect and turn on PSU
Connect PSU to the board by the Int12V connector or the Ext12V connector. Please note that current
limitations apply, see relevant connector description.
6. Power Button
If the board does not start by itself when switching on the ATX PSU AC mains, then follow these
instructions to start the board. Install the Always On Jumper in the Always On position or toggle the
PWRBTN_IN# signal (available in the FRONTPNL connector), by momentary shorting pins 16
(PWRBTN_IN#) and pin 18 (GND). A “normally open” switch is recommended.
7. BIOS Setup
Enter the BIOS setup by pressing the <F2> key during boot up.
Enter “Exit Menu” and Load Setup Defaults.
Refer to the “BIOS Configuration / Setup“ section of this manual for details on BIOS setup.
that BIOS may boot in UEFI shell, if so then type exit to activate BIOS menu and select Set-up.
Jumper for ⋲10 sec (without power connected).
leave the Power Connectors unconnected while configuring the board. Otherwise components
(RAM, LAN cards etc.) might get damaged. Make sure to use +12V single supply only.
Alternatively use a standard ATX PSU with suitable cable kit and PS_ON# active.
Please note

8. Mounting the board in chassis
components on both sides of the PCB which can easily be damaged if board is handled without
reasonable care. A damaged component can result in malfunction or no function at all.
: When mounting
When fixing the Motherboard on a chassis it is recommended using screws with integrated washer and a
diameter of ⋲7mm. Do not use washers with teeth, as they can damage the PCB and cause short circuits.
Requirements IEC60950 2.2
Take care when designing chassis interface connectors in order to fulfil the IEC60950 standard.
like the VCC plane:
To protect the external power lines of the peripheral devices the customer has to ensure:
• Wires have suitable rating to withstand the maximum available power.

LVDS Flat Panel Connector (LVDS – J31) 7.6
The LVDS connector (Flex boards only) is based on 40 pole connector type Samtec SHF-120-01-F-D-SM-KTR or similar.
Note: The LVDS connector supports single and dual channel, 18/24bit SPWG panels up to a resolution of
1600x1200 or 1920x1080 and with limited frame rate up to 1920x1200.
Signal Description – LVDS Flat Panel Connector:
LCDVCC
Notes: Windows API will be available to operate the BKLTCTL signal. Some Inverters have a limited voltage
range 0- 2.5V for this signal: If voltage is > 2.5V the Inverter might latch up. Some Inverters
generates noise on the BKLTCTL signal, causing the LVDS transmission to fail (corrupted picture on
the display). By adding a 1Kohm resistor in series with this signal, mounted at the Inverter end of
the cable kit, the noise is limited and the picture is stable.
If the Backlight Enable is required to be active high then, check the following BIOS Chipset setting:
Backlight Signal Inversion = Enabled.

The GPIO’s are controlled via the ITE IT8516F Embedded Controller. Each GPIO has 100pF to ground,
clamping Diode to 3V3 and has multiplexed functionality. Some pins can be DAC (Digital to Analogue
Converter output), PWM (Pulse Width Modulated signal output), ADC (Analogue to Digital Converter input),
TMRI (Timer Counter Input), WUI (Wake Up Input), RI (Ring Indicator Input) or some special function.
Signal IT8516F pin name Type Description
AO = Analogue Output
IOS = Digital Input or Output 4, 8, 12 or 16 mA, Open-Drain option.
O4 = Output 4mA
O8 = Output 8mA
AI = Analogue Input
IS = Digital Input

The “Always On” can be used to implement hardware controlled Always ON by jumper. When “Always On” is
selected, then the board will power up automatically when power is connected. It doesn’t matter if “Always
On” is not selected in BIOS.
The board can still be shut down by PWRBTN_IN# (power button in) activation (via Front Panel connector).

SPI Connector (SPI – J16) 7.14
The mITX-E38 provides one synchronous full duplex SPI (Serial Peripheral Interface) Bus in a 10 pin header
connector. The connector is type Pinrex 512-90-10GBE5 or similar.
