Barrel Jack Adapter - USB to 5.5mm

by Sparkfun

This is a simple cable that adapts from a USB port to a 5.5x2.1mm barrel connector, center positive. This cable allows the user to use a USB port on a computer, laptop, or on our cigarette power supply to provide our development boards with 5V.

The USB specification limits current consumption to a max of 500mA from a USB port but this is more than enough to run a simple development board.

Cable length is 3 feet.
