    Papilio latest design files

    Hello Where can i find papilio's latest stable eagle files (e.g papilio one)? Thanks.
  5. Thanks for your answer, i solved my problem. Are the design files loaded in papilio site, the working one?doesn't need any modifications? Where can i find the latest working and stable design files?
  6. Hello For production purpose, i need polygon clearance modified altium design file of papilio one (at least 12 mil clearance), after successfully importing eagle files i tried to increase the clearances but i didn't succeed. Maybe it's because of it's specific polygon pouring used for ground and power tracks.
  7. Hello Can i replace papilio pro's original SDRAM with something like samsung's K4S561632? as i checked, they are pin to pin compatible.
  8. Hello It is possible to replace 93LC46B serial eeprom with 93C46B (as i checked the difference is in supply voltage range, that is 2.5-5.5 volts for 93LC46B and 4.5-5.5 volts for 93C46B)?
