Datasheet

 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 the required 2-4A.
 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, and low quiescent
current: 5mA when enabled and power LED is on, 20µA when
disabled (power and low battery 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 2-PH JST jack, a 2-pin Terminal
block and a USB A jack.
If you are powering your project from USB, solder the USB A jack in (a
3-minute soldering task). Then choose either JST for input (JST is often
used for our LiIon batteries, but the connector is only rated for 2A) or a
terminal block.
The 1000 version comes with a 2-pin terminal block so you can solder
it to the output spot where the USB jack would go. Or don't solder any
connectors in for a more compact power pack and go with 22AWG
wires soldered directly in.
 Dimensions: 29mm x 23mm x 2mm / 1.1" x .9" x .1"
 Height w/ JST: 7.5mm / .30"
 Weight: 6.0g
