• Power
  • Four independent power rails at 5V, 3.3V, 2.5V, and 1.2V.
  • Power supplied by a power connector or USB.
• USB
  
  • Two channel USB connection for JTAG and serial communications implemented with FT2232.
  • EEPROM memory to store configuration settings for FT2232 USB chip.
• Spartan 3E FPGA
  • 32MHz oscillator that can be used by Xilinx's DCM to generate any required clock speed.
  • VTQFP-100 footprint that supports Xilinx XC3S100E, XC3S250E, and XC3S500E parts.
  • Bank 0-3 can be jumpered to support 1.2V, 2.5V, or 3.3V.
  • Xilinx JTAG header supports Xilinx JTAG cables.
  • Power and I/O are routed to the side headers.
  • Board can be used with Bread Boards if only the outside row of the side headers is populated.
• Wings
  • Easily add new functionality to the Papilio One with Wings that snap onto the board.
  • 48 bidirectional I/O lines which can be split up as:
    • 1 - 32 Bit Wing or
    • 3 - 16 Bit Wings or
    • 6 - 8 Bit Wings
