PowerBoost 1000 Basic

PowerBoost 1000 Basic

The Adafruit PowerBoost 1000 Basic (5V USB Boost @ 1000mA from 1.8V+) is the ideal power supply for your portable project.
This tiny DC/DC boost converter module runs from 1.8V batteries or higher. It can also convert that voltage to 5.2V DC to run your 5V projects. With a strong 4A DC/DC converter, it is capable of granting you 1A+ even from a low 2V.

Instead of a straight-up 5.0V, Adafruit have modified the output to 5.2V, this way there will be a little of ‘headroom’ long cables, together with high draw, if you wish, it will be possible to add a diode on the output, etc. This 5.2V product is safe for all 5V-powered electronics such as Raspberry Pi, Arduino and Beagle Bone, because, at the same time, it prevents unwelcome brown-outs during high current draw thanks to the USB cable resistance.

A TPS61030 boost converter from TI is at the core of the PowerBoost 1000. This boost converter chip have some nice extras like synchronous conversion, low battery detection, 4A internal switch, 700KHz high-frequency operation and excellent efficiency.

• Synchronous operation allows you to completely disconnect the output by simply connecting to ground the ENable pin. This will completely turn the output off.
• 4A internal switch allows you to get, from as low as 1.8V, 1000mA+, from 2 NiMH or Alkaline batteries, 1500mA+, and, from a 3.7V LiPoly/LiIon battery or also from 3 NiMH/Alkalines, at least 2000mA. Just be assured your batteries are really capable of supplying the needed 2-4A.
• Low battery indicator LED will light up red when the voltage drops below 3.2V, optimized for the most common and prevalent LiPo/LiIon battery usage.
• On-board 1000mA charge-rate data resistors ‘Apple/iOS’. By simply soldering in the included USB connector, you will be able to plug in any iPod or iPhone for a fast 1000mA charge rate. It works with either mini and ‘classic’ type of iPads.
• Full breakout for battery in, control pins and power out
• In most cases 90%+ operating efficiency (see efficiency graphs’ datasheet). It presents a low quiescent current of 5mA (when it is enabled and power LED is on) and of 20uA (when disabled and power and low battery LED are off).

Important: Always verify the polarity before connecting the battery.

Ideal for an Arduino project, powering your robot and also for single-board-computer such as Raspberry Pi or BeagleBone.

The Adafruit PowerBoost 1000 Basic (5V USB Boost @ 1000mA from 1.8V+) is shipped with a fully assembled and tested PCB, a loose USB A jack, a loose 2-PH JST jack and a 2-pin Terminal block.

If you want to power your project from USB, simply solder the USB A jack in, this will take you just 3 minutes. Then you can simply choose between either JST for input or a terminal block. Note that JST is regularly used for LiIon batteries, even though the connector is rated only for 2A.

The 1000 version contains a 2-pin terminal block. You may decide to solder it firmly onto the output spot, the spot where the USB jack would go. Otherwise, you may choose not to solder any connectors in to get a more compact power pack and simply have 22AWG wires soldered directly in.
