840 Pcs Breadboard Jumper Wires Kit, 14 Vaules 2-125mm Solderless Flexible Connecting Cables, Breadboard Connecting Line Cables, Pre-Stripped & Pre-Formed Right Angles, for Arduino, PCB Circuit Boards

Perfect for my project...although my layout skills aren't perfect :) Makes the project less prone to loose wires. *** Next I will move jumper wires to the connect point under the board, even less likely to get pulled loose. *** This project bridges from a mvave chocolate plus control pedal to a spark go amp modeler/speaker. It will be transported inside a guitar case, and then kicked around a stage.

If you're tired of the "rat's nest" look of flexible Dupont jumpers, this 840-piece pre-formed kit is a game changer. It provides a massive variety of solid-core U-shaped wires that lay flat against the breadboard, making your circuits easier to trace and debug. Assortment and Storage * The "Daily Driver" Advantage: This kit includes 14 different lengths (from 2mm up to 125mm), which is more than the standard 8 or 10 sizes found in most generic sets. Having those "in-between" sizes (like 12mm, 17mm, and 22mm) allows for much tighter routing. * Case Quality: The kit comes in a very good quality case that is sturdy and effective at keeping everything organized. It’s a nice departure from the flimsy "takeout container" plastic often seen at this price point. * Compartment Sharing: Because there are 14 values but only a few compartments, some of the smaller sizes do share space. Notably, the blue and green wires share a slot, as do the red and brown ones. It’s worth a quick glance before grabbing a handful to ensure you have the specific length you need. Wire Quality * Gauge: The wires are 24 AWG. While 22 AWG is the standard for the tightest fit, these 24 AWG jumpers perform well. They aren't the thickest on the market, but they are sturdy enough to be reused many times without the ends becoming too soft or brittle. * Pre-Formed Convenience: Each wire is pre-cut, pre-stripped, and bent at a perfect 90-degree angle, saving a massive amount of time on the bench. The Power Rail "Gap" * A Common Frustration: Despite the 14 sizes, there still isn't a "perfect" length for jumping the power rails from one side of a standard breadboard to the other. Most breadboards have a gap of roughly 1.65 to 1.7 inches. The 50mm wire is slightly too long, and the 25mm is too short. You'll still need a custom-cut wire or a flexible jumper for that specific bridge. Pros * Superior Variety: 14 sizes cover almost every component-to-component jump. * Organized Storage: Durable case keeps your workspace tidy. * Clean Layouts: Encourages flat, organized wiring that is easy to troubleshoot. * Good Value: At under $10 for 840 pieces, it’s a cost-effective bench staple. Cons * Shared Compartments: Smaller sizes are mixed, which can slow you down slightly. * No Perfect Rail Bridge: Still missing that one specific size for jumping the center trough. Final Verdict: 4/5 Stars This has quickly become my go-to kit. The quality is solid, the case is excellent, and the extra size increments make it more useful than any other set I've owned. It’s a must-have for any electronics hobbyist who values a clean, organized breadboard.

This is an okay\budget set of wires for when you are too lazy to cut your own jumper wires so they are flush with the breadboard. When I insert them into my breadboard, I can feel the "grip" when contact is made (and it doesn't fall out when inverted and shaken). Your results may vary depending on the types quality of breadboard. It IS solid stranded, but it is NOT "copper plated" I did not deduct stars for this mistake, since you can clearly see in their pictures the silver (not brown) lead wires coming out of the insulation. I would guess aluminum based on how flimsy the wires are. These are purposed for solderless breadboards, so I did not test if you could easily solder them (but since they are not copper, I suspect it will be more difficult to solder) Yes, it is flimsy\budget. Inserting the wires deforms the ends. They claim it is easier to shape, but stiffer wires can still be shaped without much effort. The container does not have tight compartments, so different colors will migrate to different compartments as the box is transported\shaken. They could have been more generous with tiny plastic bags that enclosed the smallest wires, so the medium wires are kept together as well. 5 stars = item works as described, no major complaints.

These jumper cables are decent. I have been using them and they work great. The case to hold them is no so great. I have no issues with the wires. I have been using them worth lots of diy projects. My grip is worth the case. It's just your standard light plastic screw case with compartments to hold the wires. Needless to say, the package arrived with the wires unsorted, although i imagine they were sorted. Each time I open the pack to get another, I lose more of the smallest wires. Maybe a box is better for those. Trying to find the desired color and size is always a chore as the rest of the wires replicate to another compartment. Besides that, they are good wires. They are flexible and vine in many sizes and some colors

These jumper wires appear to be solid aluminum wires that are 0.04mm thinner than typical copper core wire. I thought the narrower diameter might make for weak connects in breadboards but they seem to work ok. The problem I ran into was that the wires are so fragile and flimsy that they will collapse while trying to insert them into the breadboard holes. So while they'll work just fine once installed, getting them installed proves difficult.

I've been tinkering with Arduino setups for a while now, and this massive 840-piece pack of flexible breadboard jumper wires in 14 different lengths from 2mm to 125mm has totally upgraded my prototyping game. The pre-stripped, pre-formed right-angle ends slide right into my breadboards without any hassle, and the build quality feels super solid—durable copper cores wrapped in flexible insulation that hold up to constant bending and pulling. For the price, it's an absolute steal, giving me way more wires than I'll ever need for multiple projects without skimping on reliability. What I love most is how functional they are for everything from simple LED circuits to more complex PCB experiments. The variety of lengths and colors (like red, black, blue, and more) makes it easy to organize connections neatly, reducing wiring mistakes. Last weekend, I whipped up a quick sensor array for my robot project—plugged in the short jumpers for tight spots and longer ones to bridge power rails, and it worked flawlessly on the first try, saving me tons of time. Overall, these wires deliver huge value with their solderless convenience, sturdiness, and sheer quantity, making them a go-to for any hobbyist or maker. Highly recommend grabbing this kit if you're into electronics—it's boosted my efficiency and kept my workbench clutter-free.

This pack of breadboard jumper wires includes a good variety of lengths, all color coded. They fit well into my breadboard, but if your breadboard has looser connections, they might not work as well, because these wires are relatively thin. The wires are all pre-bent at the ends with the proper length of insulation stripped off. The plastic case that the wires come in his low profile with just enough room to hold all the wires. It snaps shut tightly with two tabs. It would have been nice if the Case we're a little bit deeper, because as it is, it is really easy for wires from one compartment to accidentally get bumped over to to an adjacent compartment. Compartment. With that said, you could also just transfer all the jumper wires to your own container if it is a significant issue. $7.99 seems like a good price for 840 pieces of various sized jumper wire.

I picked up this jumper wire kit for electronics projects, and it has been extremely useful when working with breadboards. Having a wide range of wire lengths makes it much easier to keep circuits organized instead of bending random wires to fit. It helps keep prototypes neat and easier to troubleshoot. The wires come pre stripped and pre formed with right angle bends, which makes them fit perfectly into breadboards without extra work. The connections feel solid and they stay in place well while testing different circuit layouts. It saves a lot of time compared to cutting and preparing wires manually. With so many pieces included, this kit lasts through a lot of projects without running out of the sizes you need. It is especially helpful when building or experimenting with microcontrollers and small circuits. For anyone working with breadboards, prototyping boards, or electronics learning kits, this set is a very practical addition to the workspace.
