This simple cable has so many uses
Great for Arduinos, development boards, evaluation boards, and more
Works great for Arduinos, development boards, evaluation boards and more
RoHS Compliant
The 9V to 2.1mm Barrel Jack has so many uses. Plug a 9V battery (not included) into one end and connect the other end to anything with a 5.5x2.1mm, center-positive barrel jack. Use this cable to battery-power any device that needs 9V and has an on-board barrel jack. It works great for Arduinos, development boards, evaluation boards and more.
This product seems usefull, but it is not well assembled. After connecting it 2-3 times to a 9v battery it stopped working. Closer examination showed that the black cable had detatched itself from the battery plug.
