9V to 2.1mm Barrel Jack Adapter V2
Introduction
This is the second version of the 9V to Barrel Jack Adapter. In this version the material for the 9V
battery jack is hard plastic, which makes it easier to connect and disconnect. You can plug a 9V battery
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.
