REGISTER FORUM / POWER / DC BARREL JACK ADAPTER - MALE DC Barrel Jack Adapter - Male PRT-10287 DESCRIPTION This adapter allows you to connect a barrel jack connector to bare wires. One end has screw terminals and the other has a 5.5x2.1mm, center-positive male barrel jack. If you need to connect bare wires to a barrel jack on an Arduino or a development board, this might be the simple solution. images are CC BY 2.0 SHARE DC Barrel Jack Adapter - Male Product Help and Resources SKILLS NEEDED SUPPORT TIPS Power Output last updated about 3 weeks ago These are great if you need to modify the output from a power supply and need to quickly connect the output power to an Arduino's barrel jack connector. Just make sure to test the pins with a multimeter and secure the wires. COMMENTS REVIEWS 7 0 Customer Comments Log in or register to post comments. Member #777568 / about 2 years ago / 1 I really think they're ridiculously overpriced. For this price on E-bay, one can buy 5 PAIRS of these (free shipping). So it's 10x more expensive. A 10x price margin for such a convenient product isn't very nice. Everyone should be able to have at least 10 of these lying around. I'm not trying to blame anyone or shoo people away from Sparkfun, but I'm extremely curious how the Chinese manage to sell it 10x cheaper (with free shipping from China). 532nmIsMyFavoriteColor / about 5 years ago / 1 Do you have something like this with just wires coming off instead of the weird blocky back? Kamiquasi / about 5 years ago / 1 Nope. They do have Barrel Jack to 2-pin JST and 9V to Barrel Jack Adapter for the same price that you could cut for the same effect and have a `free' 9V clip / JST connector. Though it would be more economical, and give you a greater length of wire, to get the cheaper Barrel Jack Extension Cable - M-F (3 ft) which would give you a spare female barrel jack socket. Of course you could also make your own using DC Barrel Jack Plug - Male and some wire you have laying around. waaronw / about 6 years ago / 1 I love this thing! Saves me a ton of time. My only complaint: The screw terminals are marked "+" and "-" but it would be more accurate to have them labeled as Center and Ring using the classic icon used on most wallwart transformers. Same on the female version. seulater / about 7 years ago / 1 Now That is one of the coolest things i have seen in a long while ! Quazar / about 7 years ago / 1 Dangit - I just placed an order! It seems like you always post something I want the day after I make an order.
