PowerBoost 500 Charger - Rechargeable 5V Lipo USB Boost @ 500mA+

500C Power Boost è l'alimentatore ideale per il vostro progetto portatile! Con un circuito di carica con  batteria built-in, sarete in grado di mantenere il vostro progetto in esecuzione anche durante la ricarica della batteria! Questo piccolo modulo convertitore boost DC / DC può essere alimentato da qualsiasi batteria 3.7V LiIon / LiPoly, e convertire l'uscita della batteria di 5.2V DC per l'esecuzione di vostri progetti 5V.

E'  sicuro per tutta l'elettronica-5V alimentato come Arduino, Raspberry Pi, o Beagle Bone evitando icky brown-out durante l'assorbimento di corrente a causa della resistenza del cavo USB.

Il Power Boost 500C ha un TPS61090 boost converter from TI. Questo chip convertitore boost ha alcuni extra davvero belli come il rilevamento batteria scarica, switch interno 2A, la conversione sincrona, un'eccellente efficienza, e 700kHz funzionamento ad alta frequenza. Dai un'occhiata a queste specifiche!

• Synchronous operation means you can disconnect the output completely by connecting the ENable pin to ground. This will completely turn off the output
• 2A internal switch (~2.5A peak limiting) means you can get 500mA+ from a 3.7V LiPoly/LiIon battery. We had no problem drawing 1000mA, just make sure your battery can handle it!
• Low battery indicator LED lights up red when the voltage dips below 3.2V, optimized for LiPo/LiIon battery usage
• 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.
• 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 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). 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. Or don't solder anything in for a more compact power pack.

Each order comes with a fully assembled and tested PowerBoost 500C + USB jack. Does not come with a Lipoly or LiIon battery, but we have tons in the shop, just pick one with more than 500mAh of capacity. Also doesn't come with the nice iPhone or charger cable. You can also grab a switch that can be soldered in to create an output on/off switch. Be sure to read our lovely tutorial for details, schematics, and more!
