Buck-Boost regulator

One down side of its current design is the power source needed, the boe bot barely supplies the necessary power for it to run.
Increasing memory and utilizing a buck-boost regulator to allow the javelin to run on a wider range of voltages would be nice, if there were to be ever future revisions.

Its a nice chip considering its between the stamp, sx and prop in my opinion because it allows multitasking while allowing easy to use code(java's not a hard language to learn either way though) [noparse]:D[/noparse]

    What voltage range do you have in mind?
    The javelin accepts 7.5V-24V supply. Neither the BS or the SpinStamp
    allow that upper limit.
    Also, the javelin draws about 80-90 mA so it is not really suited for
    battery operation. (The BoeBot was designed for the BS which draws
    far less current).

    its not an issue of current, but voltage, the 6 v minimum is a bit high, so 4 aa batteries is barely enough to keep the javelin from resetting on the boe bot, so maybe 4/5 v to any upper limit
