Introduction
The eSOM3735z is an easy to use 204 pin core board based on the power-efficient quad-core
Atom Z3735G processor from Intel’s 22nm Bay Trail line clocked at 1.33 - 1.83 GHz. It has 2MB
L2 cache and integrated Intel HD Graphics GPU clocked at 311MHz to 646MHz.
The eSOM3735z comes with 1GB DDR3L RAM. The Non-Volatile Memory for this PC
board is eMMC modules that plug into coreboard through two 60pin specific connectors. The
eMMC modules exist in 32GB with 8bit Bus width by default, and it is customizable with 8,16,
64GB versions. Upgrade, repair and troubleshooting in this way is easy, quick, and cost-effective
and improve maintenance ability.
The eSOM3735z integrated a PMU that reduces complexity of external power supply. Due to
board components eSOM3735z has low power consumption and can operate in industrial grade
temperature from -20℃ to +85℃.
The eSOM3735z support dual channel video output HDMI and MIPI-DSI interfaces with 24-
bit depth color resolution. This SOM has extra IO interfaces like HDMI, LCD, Ethernet, USB,
GPIO, UART, I2C that users can access them through DDR3-SODIMM 204 pin straight connector
that enables hardware customization and gives more hardware flexibility to various projects.
The eSOM3735z can boots Windows 10 very quickly and allows x86 developers to use the
single board software development without having to learn about embedded systems such as ARM
processors. Utilizing the eMMC with 8bit BUS width increased Operating System speed. In
addition, it is integrated many peripherals such as GPIOs and users challenge with microcontrollers
is eliminated.It is a perfect platform for x86 developers to make devices like Thin client HMI,
Vending Machines, IoT etc.

Development Board Setup
Follow these instructions to power on your board:
-Plug eMMC module into your eSOM3735z eMMC connector, a hole in eMMC module
and corresponding hole on coreboard is considered to users can install eMMC module in
the relevant position
-For using eSOM3735z coreboard you need to expansion board, eDVK3735z is
recommended. This board connections is shown in the following picture:

-Connect HDMI cable to HDMI Port of board. If you want using MIPI LCD, plug LCD
FPC cable to corresponding slot as shown in the following image (MIPI LCD connection
in eDVK3735z).
The eSOM3735z support both HDMI and MIPI LCD simultaneous with special
Windows 10 that released for this board.
-Plug core board into corresponding slot of your development board:
-Plug USB mouse and keyboard.
-Users need to power the developer kit with a good quality power supply that can deliver
sufficient current at the developer kit’s power jack. If you are using eDVK3735z a power
supply voltage output must be in 7.5V to 24VDC range. Plug Power adaptor into your
board.
