The Pipistrello FPGA Development Board is a Papilio One derivative designed and built by Magnus Karlsson. More info is available at http://pipistrello.saanlima.com/index.php?title=Welcome_to_Pipistrello

The big difference from the Papilio Plus is that it has more of everything, and some on-board interfaces (which are possible due to the higher I/O count of the BGA footprint.

  • The one I've got has a Spartan 6 LX45 FPGA - 500% bigger than LX9 on the Papilio Plus
  • It has 64MB (32M x 16) of LPDDR RAM on it - 128 times bigger than the 512MB on the Papilio Plus and much needed for the video interface.
  • It has on-board HDMI connector for sound and video
  • It has an audio output
  • It has a Micro SD slot.

This makes it a approximately nine times larger than any other FPGA I own.

The HDMI connector is a big boost for my projects - it allows the FPGA to generate video with 24 bit colour depth. If you attempted this with R/2R DACs it would, require 24 I/O pins and 48 resistor. It also leaves all the pins on the wing connectors available for other uses.

I've got a plans for it But first off I have to learn the TMDS protocol used by the HDMI/DVI interface...
