Overview
PowerBoost is the perfect power supply for your power-hungry portable project! This little DC/DC boost converter
module can run from 1.8V batteries or higher, and convert that voltage to 5.2V DC for running your 5V projects. With a
beefy 4A DC/DC converter, it can give you 1A+ from as low as 2V.
Like our popular
5V 1A USB wall adapter
(https://adafru.it/duP),
we tweaked the output to be 5.2V instead of a straight-
up 5.0V so that there's a little bit of 'headroom' long cables, high draw, the addition of a diode on the output if you
wish, etc. The 5.2V is safe for all 5V-powered electronics like Arduino, Raspberry Pi, or Beagle Bone while preventing
icky brown-outs during high current draw because of USB cable resistance.

The PowerBoost 1000 has at the heart a
TPS61030 boost converter from TI
(https://adafru.it/dLY).
This boost converter
chip has some really nice extras such as low battery detection, 4A internal switch, synchronous conversion, excellent
efficiency, and 700KHz high-frequency operation. Check out these specs!
Synchronous operation means you can disconnect the output completely by connecting the ENable pin to
ground. This will completely turn off the output
4A internal switch means you can get 1000mA+ from as low as 1.8V, 1500mA+ from 2 NiMH or Alkaline batteries,
and at least 2000mA from a 3.7V LiPoly/LiIon battery or 3 NiMH/Alkalines. Just make sure your batteries can
actually supply 3-4A, OK?
Low battery indicator LED lights up red when the voltage dips below 3.2V, optimized for the most common
usage of LiPo/LiIon battery usage
On-board 1000mA charge-rate 'Apple/iOS' data resistors. Solder in the included USB connector and you can
plug in any iPhone or iPod for a speedy 1000mA charge rate. Works with iPads, both mini and 'classic' type.
Full breakout for battery in, control pins and power out
90%+ operating efficiency in most cases (see datasheet for efficiency graphs), and low quiescent current: 5mA
when enabled and power LED is on, 20uA when disabled (power and low batt LED are off)

Great for powering your robot, Arduino project, single-board-computer such as Raspberry Pi or BeagleBone! Each
order comes with one fully assembled and tested PCB, a loose 2-PH JST jack, a 2-pin Terminal block and a loose USB
A jack.
