Product #: MKWL08

The Battery Booster Shield is an add-on for the Arduino that efficiently boosts a lower input voltage (0.65v to 4.5v) up to 5v. It lets you power your Arduino projects using just 2 AA batteries - perfect for making your projects portable. It will also allow you to allow solar or other alternative energy applications to power your projects.
  • Current limit is determined by the input voltage - ranges from 70mA for 0.65V up to 550mA for 4.5V.
  • Easy to assemble kit. SMT parts are pre-soldered
  • Fully open source
  • Custom, professionally made PCB
  • Build instructions, sample code, and documentation available here.
    PCB Assembly:

    Most of the soldering is already finished for the Battery Booster Shield, but you will need a soldering iron and solder to finish soldering the kit. The header pins to connect the shield to the Arduino need to be soldered in. To do this, grab any arduino shield, and stick the included long header pins to the pins on the spare shield. This will allow us to make sure the header pins are nice and straight. Slide the Battery Booster Shield onto the long header pins, making sure the components are facing away from the exposed pins. Solder the pins to the shield.

    The Battery Booster Shield includes a mini expansion header with three connections, located in the lower-left corner of the shield. The bottom pin is a connection for the LED next to it, the middle pin is a direct connection to the battery voltage, and the upper pin is for the “heart LED” in the center of the shield. You can use a little piece of wire to connect the LED pins to any arduino pin you want, and control the LEDs in software. You might use one led as a power indicator, or perhaps a blinking “low battery” alert. The center pin connects to the battery voltage, and you can connect this pin to any of the analog input pins to be able to monitor your current battery voltage. If you want to use any of these three connections, you can either solder wires directly into the holes, or you can install the included 3-pin female header pins, to allow you to reconfigure the connections.
