The Arduino VGA Shield will be, as the project name may indicate, an Arduino shield that outputs VGA video. The board itself could be based around:

  • 4D Systems µVGA-PICASO-MD1 module ($54)
    • Very expensive
    • Some complaints about reliability
    • Only talks RS232
  • Propeller chip with custom code ($8)
    • Cheap
    • Unsure how high resolution would be possible given generating VGA video from an MCU
  • Custom FPGA solution ($?)
    • More work than any other solution
    • Similar cost to propeller chip, likely
  • Off-the-shelf VGA controller chip
    • The Epson S1D13506 seems promising, you talk to it and it has an internal RAMDAC to generate video.
      • Supports LCD, VGA, and NTSC/PAL composite output
      • Flexible bus to talk to the microcontroller
  • Project Peacock
    • Hybrid CPLD/MCU solution, cheaper than using a softcore in an FPGA
    • Would allow for an easy DVI shield too
