Hi all,

I can't find on launchpad cc3200 datasheet maximum current draw ratings for +3.3v and +5v pins. Where I can find them?

    Hi,

    5V pin : It's directly routed from USB supply and depends on the source you are connecting the launch pad. If laptop, typically 500 mA.

    3.3v pin : It is derived from on board LDO with 5 v input. Please refer in combination of 5v input and LDO specs + CC3200 peak current combination together. CC3200 Peak current consumption are specified in DS.

    Regards,

    That means I can draw 500mA without damage the board? I've asked becouse I can't find LDO specifics on Launchbox Datasheet and CC3200 don't provide any informations about Launchbox.
