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.
