Temperature

About how hot can a basic stamp and carrier board get and still be fully
functional? I'm trying to put my next to a radio that gets VERY hot and I
don't want damage caused by extreme temperatures. So what kind of
temperature is the maximum for it to function at?

    David,

    The standard PIC16C56 is rated for 0-70 degrees C. Crystals and
    ceramic resonators tend to be in the same range. And don't forget
    about your power source, if you are using batteries, especially NiCd.

    I could be mistake, but I believe Parallax offers (used to offer?) an
    industrial version which had a PIC rated at -40 to +85 degrees C.

    Has anyone here ever done any tests to see how extreme temperature
    (either way) affects the Stamp's timing?

    Steve

    ok. it might be ok then... it involves placing the controller inside a
    heavy steel case next to a HOT radio.. ~120-130 degrees....
