Dragon-E PCI Express & FX2 USB FPGA board

Q3 2012 - Now with Windows WDM driver, includes source code.

In short:

  • Xilinx Virtex-5 FPGA with integrated PCI Express port.
  • Color TFT LCD with LVDS interface.
  • USB-2 high-speed interface, lots of IOs, I2C master, FlashyD compatible... and the ease of use of KNJN FPGA boards.

PCI Express and USB-2 high speed interface

The Xilinx Virtex-5 FPGA provides the PCI Express port in conjunction with Xilinx's PCI Express "Endpoint Block Plus" core. The core is included in Xilinx's free development tool ISE Webpack. The board also features an high-speed USB-2 interface allowing using the board in standalone or dual-PC mode.


Dragon-E can be used as motherboard for other projects. See here for example Dragon-E with a FlashyD acquisition board to create a two-channels acquisition system or digital oscilloscope.


Dragon-E has the option to drive an LVDS TFT LCD through its FFC connector.
