Open EP3C5-C Standard

OpenEP3C5-C Standard is an FPGA development board designed for ALTERA Cyclone III series, features the EP3C5 onboard, and integrates various standard interfaces, pretty easy for peripheral expansions. It consists of the mother board DVK601 and the FPGA core board CoreEP3C5.

OpenEP3C5-C supports further expansion with various optional accessory boards for specific application. The modular and open design makes it the ideal for starting application development with ALTERA Cyclone III series FPGA devices. OpenEP3C5-C enables you to start your design with the Nios II processor easily and quickly.
