Adafruit Breadboard-friendly 2.1mm DC barrel jack

This power jack is engineered to secure 2.1mm power plugs seamlessly, preventing disruption in your electronics project. Its "thin pin" design provides a perfect fit for breadboards and perfboards, ensuring compatibility where "thick pin" types are used with a touch more solder.

The jack features a positive end pin, a negative middle pin, and an innovative side pin that switches function: inserting a plug causes it to float, while removing it connects it to the negative pin. Experience reliability and precision in power connectivity for your next innovation.
