If you would like to use a terminal block, pick up a 3.5mm 2pin block here and solder to the output spot where the USB jack would go. If you are powering your project from USB, solder the USB A jack in (a 3-minute soldering task). 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 and a loose USB A jack. Not suggested for iPad (which really needs 1A charge rate).įull breakout for battery in, control pins and power outĩ0%+ 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) Solder in the included USB connector and you can plug in any iPhone or iPod for 500mA charge rate. On-board 500mA charge-rate 'Apple/iOS' data resistors. 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 This will completely turn off the outputĢA internal switch (~2.5A peak limiting) means you can get 500mA+ from as low as 1.8V, 750mA+ from 2 NiMH or Alkaline batteries, and at least 1000mA from a 3.7V LiPoly/LiIon battery or 3 NiMH/Alkalines. Synchronous operation means you can disconnect the output completely by connecting the ENable pin to ground.
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. The PowerBoost 500 has at the heart a TPS61090 boost converter from TI. 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. Like our popular 5V 1A USB wall adapter, 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.
#Is eyeframe converter safe portable
PowerBoost is the perfect power supply for your 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.
