Do you fear that your power may not be “far reaching” enough? How would another 3' work for you? Okay, so it doesn’t sound very dramatic, but sometimes an extra 3' of power cable is exactly what your project needs. Don’t hack apart a nice clean barrel jack connection just because it won’t reach, this male-to-female barrel jack extension cable will make the reach.
This cable is terminated with 5.5x2.1mm barrel connectors, one male and one female, and fits most of our products that use a DC barrel jack for power (RedBoard, RaspiRobot board, etc.)
Dimensions: 3' Long, 5.5x2.1mm Barrel Connectors
