Xilinx Kintex UltraScale FPGA PCIe Board

The XpressKUS-95-Gen3 from REFLEX CES is a full height PCIe 3.0 x8 Board featuring HPC FMC interface flexibility for an FMC daughter board and a DDR3 SODIMM connector.

The board is based on the Xilinx Kintex® UltraScale KU095 FPGA, and has been optimised for both prototyping and field deployment. 

The XpressKUS allows for ease of use when designing prototypes, including a PCIe controller. The board is designed for prototyping, deployment, and is backward compatible to PCIe 2.0 and PCIe 1.1.
