With a built-in battery charger circuit, you'll be able to keep your project running even while recharging the battery! This little DC\/DC boost converter module can be powered by any 3.7V LiIon\/LiPoly battery, and convert the battery output to 5.2V DC for running your 5V projects.\u003c\/p\u003e\n\u003cp\u003e \u003ca href=\"https:\/\/www.adafruit.com\/products\/2465\"\u003eIf you need a 1A battery charger, smart load-sharing, and 1A iOS resistors, check out the Powerboost 1000C\u003c\/a\u003e\u003cbr\u003e \u003cbr\u003eLike our popular \u003ca href=\"https:\/\/www.adafruit.com\/product\/501\"\u003e5V 1A USB wall adapter\u003c\/a\u003e , we tweaked the output to be 5.2V instead of a straight-up 5.0V so that there's a little bit of 'headroom' for 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.\u003cbr\u003e\u003cbr\u003e The PowerBoost 500C has at the heart a \u003ca href=\"http:\/\/www.ti.com\/product\/tps61090\"\u003eTPS61090 boost converter from TI\u003c\/a\u003e . This boost converter chip has some really nice extras such as low battery detection, 2A internal switch, synchronous conversion, excellent efficiency, and 700KHz high-frequency operation. Check out these specs!\u003c\/p\u003e\n\u003cul\u003e\n\n\u003cli\u003e Synchronous operation means you can disconnect the output completely by connecting the \u003cstrong\u003eEN\u003c\/strong\u003e able pin to ground. This will completely turn off the output\u003c\/li\u003e\n\n \u003cli\u003e2A internal switch (~2.5A peak limiting) means you can get \u003cstrong\u003e500mA+\u003c\/strong\u003e from a 3.7V LiPoly\/LiIon battery. \u003cstrong\u003eWe had no problem drawing 1000mA\u003c\/strong\u003e , just make sure your battery can handle it!\u003c\/li\u003e\n\n\u003cli\u003e Low battery indicator LED lights up red when the voltage dips below 3.2V, optimized for LiPo\/LiIon battery usage\u003c\/li\u003e\n\n\u003cli\u003e Onboard 500mA charge-rate 'iOS' data resistors. Solder in the USB connector and you can plug in any iPhone or iPod for 500mA charge rate. Not suggested for large iPads.\u003c\/li\u003e\n\n\u003cli\u003e Full breakout for battery in, control pins and power out\u003c\/li\u003e\n\n\u003cli\u003e 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)\u003c\/li\u003e\n\n\n\u003c\/ul\u003e \u003cp\u003eTo make this even more useful, we stuck a MicroLipo charger on the other side. The charger circuitry is powered by a microUSB jack, and will recharge any 3.7V\/4.2V LiIon or LiPoly battery at 500mA max rate. There's two LEDs for monitoring the charge rate, a yellow one tells you its working, a green one lights up when its done. You can charge and boost at the same time no problem, without any interruption on the output so its fine for use as a \"UPS\" (un-interruptable power supply) for a low-current draw device. Just be aware that the charge rate is 500mA max, so if you're drawing more than ~300mA continuously from the 5V output side, the battery will slowly drain since the charge rate is less than the dis-charge rate.\u003c\/p\u003e\n\u003cp\u003e Please note that this board is designed to be used only with a LiPoly attached, it won't work without a battery.\u003cbr\u003e \u003cbr\u003eGreat 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 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). \u003ca href=\"https:\/\/www.adafruit.com\/product\/724\"\u003eIf you would like to use a terminal block, pick up a 3.5mm 2pin block here\u003c\/a\u003e and solder to the output spot where the USB jack would go. Or don't sold anything in for a more compact power pack.\u003cbr\u003e \u003cbr\u003eEach order comes with a fully assembled and tested PowerBoost 500C + USB jack. Does not come with a Lipoly or LiIon battery, \u003ca href=\"https:\/\/www.adafruit.com\/categories\/138\"\u003ebut we have tons in the shop, just pick one with more than 500mAh of capacity\u003c\/a\u003e . Also doesn't come with the nice iPhone or charger cable. You can also \u003ca href=\"https:\/\/www.adafruit.com\/product\/805\"\u003egrab a switch that can be soldered in to create an output on\/off switch\u003c\/a\u003e .
