It offers versatile peripherals, such as ethernet, usb device, usb host etc. The board also incorporates a power supply and is a Power over Ethernet (PoE) Powered Device (PD). Additionally, a Cyclone III FPGA from Altera is integrated on the board. The FPGA is mapped into the 32-bit AVR memory bus. The FPGA offers two DDR2 SDRAM interfaces, which will cover even the most exceptional need of memory bandwidth. Together with the onboard video decoder the board is ready for video processing.
