Xilinx Spartan3, XC3S1500 FPGA stand alone FPGA development board, especially developed for LEON development, with on-board SDRAM, FLASH, Ethernet, Video DAC, USB, 2x PS/2, 2x UART, PIO, user and memory expansion connectors

This board is also available with a larger Spartan3 XC3S2000 FPGA. However, please note that, whereas the XC3S1500 is supported by the free Xilinx Web-pack tools, it it necessary to have the full Xilinx ISE software suite to be able to synthesise and program designs on to the XC3S2000 board.
