Thanks to the conveinent USB interface on most Arduino and compatible boards, it's easy to find a suitable power supply - either from a PC, external battery pack or by using an AC-USB adaptor that's supplied with most new mobile phones. However for more portable situations where mains current isn't available, the rechargeable or AC options can't be used. The solution to this has been quickly demonstrated by Instructables member tzq33tdq who uses our USBboost module to convert the power from 2 x AAA cells to a 5V USB-compatible outlet.
If you're looking for a way of providing a USB-style 5V power supply from lower voltages such as those that can be found from rechargeable batteries or packs of AA cells then check out our USBboost module. It can generate 5V from anywhere between 1.2 and 4.5V, and offer a full 500 mA of current from supply voltages above 2.4V. Plus it has preset low-battery levels you can select with logic output to tell your project when the device should power-down - and of course it can power an iPod. So for more information and to order, check out the USBboost page.
