    I need to know how many mA of current do you want the adapter to supply?

    im not sure yet.
    based on this chart i could potentially need 30+?

    and other than that the BT chip i plan to use uses something like 27.

    what would you suggest?

    The current version can support 650mA for 3.3V. Just place the order on my website with a note to tell me 3.3V is needed. No price difference.
