The evaluation board for SoC51 features different components and connectors that are useful for your first SoC design:

• Altera Cyclone FPGA (EP1C12F256C7)
• Interface connector for DProbeHS
• 4-digit 7-segment LED display
• RS232 interfaces consisting of a female D-SUB 9-pin connector and a level converter (MAX232)
• USB peripheral interface consisting of USB controller (FTDI245B) and B-type receptacle connector
• Expansion connectors with 48 general-purpose I/O signals for user-added hardware
• Download connector for the Altera Byteblaster
• Frequency generator with 4 fixed frequencies, selectable through a DIL switch
• Boot PLD with external FLASH memory for stand-alone operation

The board doesn't need a power supply as it is powered by the attached DProbe in-circuit emulator.
