SerPlug

SerPlug is born!

A Brief History of SerPlug:

Over the years I have seen many questions about serial programming circuits for the Propeller. Personally, I’ve tried the two and three transistor circuits – unfortunately I found that they did not work with all USB to Serial cables. That’s why I designed a MAX3232 based RS232 programming circuit for my Mem+ board. At the same time, I also laid out (in Eagle, in case any one is curious) a stand alone version; however I assumed that most people who got a Morpheus board would get a Mem+, or would already have a Propeller Plug.

Late last year, I showed a preliminary layout to Sapieha … and he kindly offered to make a nicer layout for me. He was right, his layout is nicer than mine was.

Off it went to prototype production… and today I got the prototypes.

I am happy to announce that the SerPlug is now in stock and ready to ship!

  • SerPlug has a 3 pin jumper for choosing RTS or DTR as the RESET signal
  • SerPlug has a RSTEN jumper, which if removed, stops the Propeller from being reset.

SerPlug’s 5 pin header is PropPlug compatible, with the addition of a fifth pin that supplies +3.3V to SerPlug. If you are programming a board that only has a 4 pin connector, simply run +3.3V to the fifth position.
