General Description

Embest SBC6845 Single board computer is a high-performance ARM embedded single board computer (SBC) with popular ATMEL AT91SAM9G45 Processor. It is a compact board with frequently used functions and also with small size. It is designed for a wide range of applications including Industrial Control Terminal, Intelligent Instrumentation, Data Acquisition and Analysis, Medical products,.Network Terminal, etc.

The SBC6845 Single board computer has 128MBytes DDR2 SDRAM, 256MBytes Nand Flash and 4MBytes Data Flash on board. It extends many hardware interfaces including serial ports, USB Hosts, CAN, RS485, Ethernet, SD card, Audio out, keypad, LCD, Touch screen and etc.

Embest offers 4.3 inch and 7 inch size LCDs including touch screen for options, user can connect the LCD/TSP through one 2.54mm pitch 2*20-pin connector on board, the driver has already provided and user can use it already. If user wants to use large size LCD with the SBC6845 board, Embest also offers one RGB-to-LVDS converter board as an option which can convert the LCD RGB signal to LVDS signal to create the large size LCD connection possibility.

The SBC6845 Single board computer is ready to run Linux 2.6.30 open source operating system and WinCE 6.0 operating system. We provide Linux source code, WinCE BSP, User Manul and part of development tools to help customer with their own development. So the board is a stand platform ideal for evaluation and early development work. The board also has a compact and logic layout and user can use it directly for their next embedded design which can help to shorten the time from embedded board to products.
