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.

Two pin JST connector to a 2.1x 5.5mm barrel jack, 6.25 inch long jumper cable. We use this cable to adapt from a wall power supply to a relatively small, SMD JST connector. We found that many of the SMD connectors used for battery charging were too large or were not capable of through-putting the current we wanted for faster charging. This setup, with a SMD JST connector and wall power supply, can handle up to 2A!
