The Lilypad Arduino USB requires between <strong>2.7 and 5.5 volts</strong>.
If I insert a AAA battery, that's <strong>1.5V</strong>.
The description says: <em>"Pop in a AAA battery, flip the power switch, and you will have a 5V supply to power your LilyPad circuit"</em>.
Does this mean it will <strong>scale up my 1.5V to 5V</strong>? and thus I'll be able to power my Lilypad Arduino USB.
Or does the sentence mean I can insert in the clip any battery between 1.5 and 5V? And then if I put 1.5V, I get 1.5V, which is not enough for the LilyPad Arduino USB.</p>

Or would you have to connect a Lipo charger for this to recharge a battery? And if it doesn't recharge it, does it have a terminal to connect a charger? Or is this just a basic power supply for the board, with no charging capabilities at all? I know the Lilypad Lipower says you can connect a Lipo charger to it so you can recharge the batteries, too, but I'm kind of confused about this one because it says a lithium polymer battery is a good rechargeable alternative to AAA battery, but doesn't say if the battery has to be charged separately.</p>

Specifically, it uses the <a href="http://www.onsemi.com/PowerSolutions/product.do?id=NCP1402" rel="nofollow">NCP1402</a> that will boost up from as low as 0.8V (even lower, but it requires 0.8V start-up) to 5V with just a few extra components (most importantly, the inductor). It does so at a detriment to battery life (the boost circuit will draw more current from the battery than the device you're powering needs), and a bit of lowered efficiency than if you were to use a 5V battery to begin with.</p>

I've bought your AA clips, but really need the smaller AAA ones</p>
