1Product Overview
1.1 Introduction
The SBC8140 is a Single Board Computer designed by Embest using the
MINI8510 processor card as the CPU core board. The MINI8510 is built
around the DM3730 microcontroller featuring 256MByte DDR SDRAM,
512MByte NAND Flash, RTC, LEDs, Camera interface and a 10-pin JTAG
interface on board. It is connected with the SBC8140 expansion board
through two 1.27mm space 2x45-pin dip connectors. The SBC8140
expansion board utilises many of other features of the DM3730 through
headers and connectors including serial ports, USB Host, OTG, Ethernet,
Audio In/Out, Keyboard, LCD/Touch Screen interface, VGA, SD card, etc.
The board targets those applications requiring high definition video or
large-scale data processing such as:
2D/3D game console products,
Portable media devices,
High-end industrial equipment,
Medical devices,
Intelligent home systems.

Appendix 1: ESD Precautions &
Handling Procedures
Please note that the board comes without any case/box and all
components are exposed. Therefore, extra attention must be paid to ESD
(electrostatic discharge) precautions. To effectively prevent electrostatic
damage, please follow the steps below:
Avoid carpets in cool, dry areas. Leave development
kits in their anti-static packaging until ready to be
installed.
Dissipate static electricity before handling any system components
(development kits) by touching a grounded metal object, such as
the system unit unpainted metal chassis.
If possible, use antistatic devices, such as wrist straps and floor
mats.
Always hold an evaluation board by its edges. Avoid touching the
contacts and components on the board.
Take care when connecting or disconnecting cables. A damaged
cable can cause a short in the electrical circuit.
Prevent damage to the connectors by aligning connector pins before
you connect the cable. Misaligned connector pins can cause damage
to system components at power-on.
When disconnecting a cable, always pull on the cable connector or
strain-relief loop, not on the cable itself.
Warning:
This is a class A product. In a domestic environment this product may cause
radio interference in which case the user may be required to take adequate
measures.
