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.
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. 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
* 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, 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
* 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'
* 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.
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…more
