ATMEL SAM9G45 ARM9 Board - evaluation board with 4,3'' TFT
Wycofany
The ATMEL SAM9G45 Board produced by Embest is a full-featured evaluation board based on the ATMEL' new processor – AT91SAM9G45 which runs at up to 400MHz, with 128 Mbytes DDR2 memory and 256 Mbytes SLC NAND Flash. The board provides a wide range of peripherals, including a high-speed USB host/device port, an Ethernet 10/100 interface, two high-speed SD/MMC slots and a QVGA 320x240 LCD panel with Resistive touch screen. In addition, the board supports Linux, WinCE and Android OS and offers plenty of example applications under these three OS, makes engineers easy to develop their project based on this AT91SAM9G45 processor.
