HiLetgo200pcs/5 * 40pcs Breadboard Jumper Wires Prototype Board Dupont Wire Male to Male, Male to Female, Female to Female 20CM Length FIVE TYPE

Great pins, checked them with some high quality ones i got from a hobby store near me, and they interconnect really well, so probably made to a high tolerance. The double pin ones were quite unexpected, i should have read the description better, but are great for LEDs testing and similar things, a lot of pin headers are that pitch too, which makes them really useful for, for example, hooking up an ESP8266 board works really well with these, as it's just 4 of these next to each other and you have all the pins broken out

0.3 to 0.4 Ohms per 20cmMetal ends are secure but the male end do move in/out by approx 2mm (not so good when trying to make a quick secure connection)For the price I wont fault them, just don't expect them to be as good as RS Dupont wires

my only dislike is the size of the pins. Let me explain: I used the wires as hookups between microprocessor assemblies and plugin breadboard. I found the pins tended to wobble about considerably which affected connections on the breadboard. Apart from that the wires did meet the purpose for which I bought them for.

Essential for anyone trying to get to grips with Arduino, Microbit or RaspberryPi.

Does the job and good value for money

A great product, well used.

Very good, used to wire my pc.

Great.

Niente di nuovo su questi tipi di prodotti pero' e' stata gradito il fatto che la parte in plastica nera, cioe' quello a contatto con il sensore / raspberry / arduino hanno una lunghezza variabile quindi nel caso si avesse poco spazio si puo' valutare se utilizzare una lunghezza piuttosto che un'altra

No parecen malotes. A ver que aguantan

pessimo! i collegamenti doppi non sono compatibili con arduino. scarsa tenuta dei singoli. i fili sembrano ricoperti di plastica rigida

purtroppo si rompono

Relación calidad-precio estupenda, conexiones firmes y buena calidad del cable, largo aprox. 20cm.

good value

Il prodotto è arrivato ed è come descritto.

Les fils 2.54mm vers 2mm sont intéressants à avoir sous la main (XBee...), même si les connecteurs coté 2mm sont regroupés par deux.Les fils sont sertis correctement (pas soudés) et résistent bien à l’arrachement.

These are much better quality than the cheap jumpers that came with one of my breadboard kits. You can see the difference in my photo. I like that the Dupont connectors are made specifically to fit both the breadboard and headers on devices. They fit well and line up nicely when you have a bunch next to each other. I don't currently have a use for the 2.0mm jumpers, but at the price it was worth getting them in case I need them later. This set was the same price as many of the others that don't include the 2.0mm. Why not get them to have if you need them later?

I spent months trying to hand make Dupont connectors, mostly making bad ones. I went ahead and bought these professionally made connectors and they are much better than my handmade ones. They are very dependable, don't pull loose or come apart. I'll be buying more.

Great quality, versatile in all sizes and colors.These "Jumper Wires" are great (to put it in a simple word), I used them for my 1-U Dell server fan cooling build.Servers come with their own proprietary plugs and my goal was to silently cool my server with big Noctua fans because the small server fans sounded like a jet engine in my living room, so i had to figure out a way of nicely connecting the Noctua Fans to the exposed pins on the server's motherboard, the that's why i chose these "connectors".Highly recommending you all of buying a few in advanced like i did because they really come in handy.Good luck to you all.

PERFECT! I was able to connect a USB to TTL cable that had 2.54mm Dupont female connectors to a port that had a 2.0mm 4 pin connector by using this kit! :) The crimping is PERFECT on this cables.

Got these to replace the stock wires in an arduino clone experiment kit. These are nice, throwing the kit wires away.

Product quality is good. right for the price.

as advertised, and of good construction, only missing 1 end cover which is not a problem, a must have and a big time saver.
