PowerBoost 1000 Basic - 5V USB Boost @ 1000mA from 1.8V
DC / DC boost voltage converter. Input min 1.8V, output 5V (5.2V to be exact) at 1000mA (if there are 1.8V inputs). If your project requires more current, for example 2000mA from 3.7V lithium batteries, make sure they can supply it. A solder-on USB connector is included.
