Jumper Wires Standard 7" M/M - 30 AWG (30 Pack)

If you need to knock up a quick prototype there's nothing like having a pile of jumper wires to speed things up, and let's face it: sometimes you want quantity over quality. These are the same jumper wires that come with the SparkFun Inventor's Kit, they're less rugged than the premium jumper wires but they're great for bread-boarding, they're less expensive and we sell them in packs of 30! They may not hold up to year after year of abuse but they're a good value and we use them all the time here at SparkFun, both in classes and personal projects. Your pack of 30 jumper wires will be a random assortment of various colors.

SparkFun Inventor's Kit Experiment Guide - v4.1

August 8, 2019

The SparkFun Inventor's Kit (SIK) Experiment Guide contains all of the information needed to build all five projects, encompassing 16 circuits, in the latest version of the kit, v4.1.

Pin Size

Compared to the premium jumper wires, the pins on these jumper wires are smaller. This can be useful for accessing smaller pitched plated through holes that are not your standard 0.1" headers.

We welcome your comments and suggestions below. However, if you are looking for solutions to technical questions please see our Technical Assistance page.

  • Could you give me datasheet?

  • What are the wire colors in the 30 pack? Are we able to choose the color?

  • Diameter of pins are about 0.60mm.

  • I've found another way to use these: if I need to use something that isn't compatible with a solderless breadboard (for example, an RFM12B, Sparkfun #WRL-12031, which has 2mm contact spacing) I'll cut some of these jumpers in half (more or less), strip the cut end, and solder it onto the part. I can then easily plug the other end into the breadboard. (The old solid wire jumpers would either break or pull off the plating on the device, and stranded wire is too hard to plug into the breadboard.)

    I'll admit that I have recently switched to using things like PRT-12795 to get more colors. But then again, I do a fair number of breadboards.

    • I should expand a little on the technique I use: I "tin" the wire with it held in a "third hand", then put the part in the "third hand", and if it isn't through-hole, I tin the part leaving a [very] little more solder than I would if I were just tinning it, then I can hold the wire in place and apply the soldering iron to the joint, and not have to juggle having the solder in hand. If you do this fairly soon (like a few minutes), the solder won't have time to oxidize enough to require additional flux. (I usually tin all the wires, then put the part into the "third hand" to complete the task.)

  • Good wire, but then I've never used the premium. I got two packs but I've never had to open the second. I did cut one wire open and it's stranded copper wire(which didn't really work for the PTH soldering I had wanted to do with it).

  • Does the job just as it should do.

  • A classic case of getting what I paid for. I have some of the premium wires and really like them but large quantities can become expensive so I bought some of these to supplement. I struggled for most a night trying to get an SPI connection to work to no avail. I took a time out to work on a project for my wife's childrens choir and got stuck on one LED forever until I relaized it was the jumper that was bad.

    I have not gone back to check on my SPI project since I used that Arduino for the choir project and it was all taken apart. In hindsite I wish I had used the Arduino that had a known good project connected to it.

    Just a note to help others. Test each one before you use it. I don't have a multimeter at home so I just set up a quick always on LED and try each jumper on that circuit before using. This would have saved me several hours of heartache.

  • I prefer jumper wires like this. When I was using the normal ones with a square plastic end I couldn't get data consistently to my shift registers from my arduino. When I use these jumpers my circuit works properly every time!

    • Does anybody know where I can find the wire these jumper wires use on a spool of a few feet/meters long. I often need thin and very flexible wires on various projects, and I mostly end up cutting the ends of those jumper wires and use the bare wire. But this ends up quite cheap.

      Here at SF they sell some wires but I don't know if they are as thin and flexible as the wires used in this product.

      • Well what you are looking for is hook up wire. If you want it to be flexible then look for stranded hook up wire as it is more flexible than solid which is very stiff.

        You can find it here

        Or if you require a larger roll, many surplus electronics sites sell this stuff in rolls of 25 ft. and up for a pretty good price.

OK for a pack of wires

Out of the 30 wires, 6 have ends that either lost the plastic insulator or the whole pin/insulator was missing. I knew they weren't 'premium' grade but I expected them to be assembled and complete on arrival.

Absolute trash

These jumpers are garbage. They seem nice at first glance, but the tips are all coated with a micro-thin layer of glue that makes them conduct poorly and randomly. They're useless unless one goes through the tedious process of cleaning/tinning all the ends prior to use.

Hi, This is the first time we have heard of this issue. We've sold literally hundreds of thousands of these and this is the first complaint about a micro coating of glue. Give us a call or email and we can help you out with this issue. Thanks

Worth owning!

They are as described .... very useful for those quickies .... and the price can't be beat. Use to make my own .... not anymore.

not bad

These are pretty good, the variety of colors is really useful. I wish the diameter of the end pieces of metal were wider so that they would stick more firmly in the breadboard.

Great for prototyping on small breadboard

I bought both these and a set of the fixed length wires that are bent into position. Both are good, but these jumper wires tend to be more versatile for fast prototyping on a breadboard.

Great quality

I'm pretty rough on the components I can be rough on and save my concern for those that need it. So for Jumpers, I yank at them and toss them into my tool box with abandon. These ones are really durable and have so far held up really well to multiple redesigns and project break downs.

Recommended for prototyping

I have been using this wires jumper for years in my prototyping projects. They save me a lot of time and they just work well .

good wires

Not sure what else to say. I used all 30 in a prototype and they all worked.

Good Quality

They are jumper wires, so there isn't much to be said, but I never had a problem with them and they stuck to my breadboard holes well.

Well made and plenty of them.

Good purchase....also got the female versions. Handy!

Nice product and excellent delivery.

They do there job

There a lot better that those wires I used before thay were kinked and twisted into every shape but straight. I just wish that the jumpers were the same amount for each color such as more green ones for rgb stuff.

Like them

I like these, but my middle school students seem to have a talent for pulling the ends off. Sturdy, just wish they were a little bit more so...Used by multiple classes throughout the day, so this is a nice replacement pack for when students get too forceful.

Great wires for quick prototyping!

Great pack of wires for easy bread boarding. Variety of colors, seem inexpensive to me. Good buy.

Super handy

I no longer have to chase down some wire and strip it for my proto-box. Just grab and plug. The different colors make it easy to trace the wires for changing.
