    Eh, the PWMPal only costs about $25 right? And I don't work for parallax.

    Knock yourself out -- give it a try.

    Hello,

    The output ratings of the PWMPAL pins can be gotten right from the SX20 datasheet on our website. I hope this helps. Take care.

    The PWMPAL has it's own voltage regulator, correct?
    I would like to get another BS/2 with PWMPAL and run them off a 9 Volt battery on a Stamp 2 carrier board (which apparently has no regulator).
    Then I could plug that into my Windows PC and record the output as .wav files, while leaving my present dos setup intact for programming.
    (I'd use a floppy disc to transport the programs)

    The PWMPAL does not have its own regulator. It gets its power from the BS2 Module plugged into it. Nonetheless you could use the carrier board since the BASIC Stamp will use its own on-board regulator. Always be careful of how much current you draw from the I/O pins when something is running from the BASIC Stamp 2 regulator. Take care.

    So to make the battery last longest:
    Highest possible value for ballast resistors
    AND .....
    Put an END after the program ?
