EDX-303 is Xilinx's Hi-performance USB-FPGA Spartan-7 board. It's compact and very simple. 5.0 V external or USB Bus power supply operation. FTDI's FT2232H (Dual channel USB controller IC) is equipped. One channel is available for a user communication interface. The other channel is configured as an I/F for FPGA configuration and configuration device access.

No download cable is needed with original configuration tool " BBC [EDX-303]".
