The AA Power board is a neat board for generating 3. 3V from a single AA battery (Alkaline or NiMh), sufficient to power a JeeNode, for example. The board uses a wide input range LTC3525 boost regulator chip which draws only 7.. 30 A of current in idle mode (depending on input voltage). The input can be anything from 1. 0 to 5. 5V, so this can also be used with 2x or 3x AA battery packs (even
