This 4-Lane PCI Express platform is designed for rapid development with Xilinx Spartan-3 (XC3S4000) PCI Express controller IP core, and external PHY (GL9714).

Two DDR SO-DIMM connectors (soldered on the back) provide generous amount of memory. The DDR Memory Controller IP Core is available through HiTech Global.

The Prototyping Area, Sub Board, and User AUX Connectors can host different daughter cards and modules.
