Description: This is a SparkFun exclusive! These are 155mm long jumpers with male connectors on both ends. Use these to jumper from any female header on any board, to any other female header. Combine these with our female to female jumpers to create a male to female jumper. Multiple jumpers can be installed next to one another on a 0.1" header. Comes as 1 package of ten jumpers (colors shown).

Dimensions: 155mm +/-5mm long

  • I have two packages of these & the F/F adapters - they are a huge time saver & worth every penny.

  • Much cheaper M/M: http://www.makershed.com/ProductDetails.asp?ProductCode=MKSEEED3 75 for $7. They don’t seem to have F/F though.

    • Hmmm: Much cheaper M/M: http://www.makershed.com/ProductDetails.asp?ProductCode=MKSEEED3 75 for $7. They don’t seem to have F/F though.
      Yes, the 75 for $7 seems like a much better deal until you spend 5 hours debugging a circuit only to find a bad jumper wire. I have had these wires fail twice now so I no longer use them. The cheaper wires broke underneath the rubber where they are crimped to the tips. The rubber continued hold on the tip and conceal the damage so they still looked and felt normal.
      I have had no such issues with the premium wires from sparkfun.

      • 5 hours? Next time use a multimeter. Cont tests are tedious but they get the job done quickly.

  • i’ve just tested them and they’re really very useful! great for quick works and testing!

  • I’d love to see 6" lengths of these M/M wires in a 100 pack. I’d also like to see 3" M/M lengths available in any quantity, especially 100 packs.

  • It sure would be nice to have the male and female ends so I could make my own custom length jumper wires.

  • Where would I get like, the ends of these?

  • I would have thought it would be more cost effective to just cut a piece of wire

  • Excellent product.

  • I just had a chance to compare these side by side with the cheaper ones mentioned by some commentators here.
    The cheap ones really are garbage. The connectors are terrible and fall apart after just one or two uses and then require five or ten minutes with a soldering iron to repair.
    These from Sparkfun really are worth the price. They have nice, sturdy connectors.

  • I bought a bunch of female-to-female jumpers and some long breakout headers. Now I can make any type of jumper.

  • Look for the Tyco/AMP “AMPMODU Mod IV” series connectors.
    Here is the product info page for the 1-pin version (even though the picture shows 12 pins): http://tinyurl.com/2ahg8eu

    • I purchased a large set of the above product suggested from Digikey, but they still do not fit correctly. The outside dimensions almost match from the specifications sheet, but the inside does not allow the pins to fit properly. I have had better luck ordering from Jameco with this particular family of connector housings Jameco Discrete Wire Housing (2 position). I hope this helps.

  • Can anybody suggest where I can buy the terminals and black plastic sheaths these connectors use, along with the handtool required to fix the terminals on to the wire?

    • I’d be interested to know that too - even better, multi-pin variants of this plug, that could be put on ribbon cables, to connect to the IDC plugs that fit IC sockets … or breadboards

  • My local electronics supplier sells these too - for $19.95. I wonder what they’re smoking.
    Thanks SparkFun.

  • Can these fit into Arduino Mega and Breadboard?

    • Yes, the black ends are exactly 0.10" the same spacing as holes on breadboards and Arduino header pins.
      I have another set of jumper wires that I really want to like, they’re really flexible and come in exactly the right lengths, but the molded ends are just slightly too big to use next to each other in headers or breadboards. Needless to say the ones listed here get a lot more use.
