Alex Raimondidd5e1332008-12-09 16:17:13 +0100131 It offers versatile peripherals, such as ethernet, usb device, usb host etc.
132
Matt LaPlante692105b2009-01-26 11:12:25 +0100133 The board also incorporates a power supply and is a Power over Ethernet (PoE) Powered
Alex Raimondidd5e1332008-12-09 16:17:13 +0100134 Device (PD).
135
Matt LaPlante692105b2009-01-26 11:12:25 +0100136 Additionally, a Cyclone III FPGA from Altera is integrated on the board. The FPGA is
Alex Raimondidd5e1332008-12-09 16:17:13 +0100137 mapped into the 32-bit AVR memory bus. The FPGA offers two DDR2 SDRAM interfaces, which
138 will cover even the most exceptional need of memory bandwidth. Together with the onboard
139 video decoder the board is ready for video processing.

153 The boards are designed to be used in a man-machine
154 interfacing environment, utilizing a touch-based graphical
155 user interface. They host a vast range of I/O peripherals as
156 well as a large SDRAM & Flash memory bank.
