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.
This simple cable has so many uses! Plug a 9V battery into one end and connect the other end to anything with a 5.5x2.1mm, center-positive barrel jack.
This simple cable has so many uses! Plug the 9 volt battery clip onto a standard 9V battery and connect the other end to anything with a 5.5x2.1mm, center-positive barrel jack.
This DC power jack/connector is just like the other one that we carry except that it’s terminated with breadboard-friendly pins instead of wide solder terminals. These are also compatible with our DC wall supplies and have a 5mm jack, with a 2.1mm center pole diameter.
Switchmode power supplies offer several significant advantages over traditional linear transformer power supplies.They are far more efficient than their linear counterparts. As they do not use power or mains transformers the equivalent power supply weighs considerably less than traditional types
We use barrel jacks a lot around here and sometimes we need to pop a switch into the mix. That usually means hacking up a perfectly good barrel jack extension cable, but the whole point of using the barrel jacks was so that we wouldn’t have to hack things apart… Well, we found a solution: The Barrel Jack Power Switch.
