Hi all,

 

I've been searching high and low for the below jump wires that I saw on Digikey, but Digikey charges an arm and a leg for them.  I would like to know what the exact name of this type of jumper wire, besides the generic name of female-to-female jumper wire.  I have a couple pieces and they seem to be very high quality and fit nicely into standard header pins.

 

If you know where to get them at good price, I would appreciate the link.  THANK YOU!

I use these - 40 F-F jumper Dupont wires for about $1.50 US.    Ebay reference: https://www.ebay.com/itm/NEW-40-...

 

They aren't very good because the inner clamps bend out after a few insertion cycles.   However pushing on the bent inner-clamp piece with the tip of a sewing needle restores them to useable status.

 

For prototyping I recommend instead the old-fashioned AWG30 gauge wire-wrap wire and the corresponding spinning tool.   Like all precision machinery, the wrapping/spinning tool is expensive (@ $30 USD) and could probably work as well if it were made of stiff plastic and sold for $4.  But the connection is a good as a solder joint (yeah, within reason) and the wire-wrapping is easier to work with if you don't have an expensive precision soldering station like a Met-Cal.   I have 30-year-old wire-wrap prototypes that still work well.  But what can anyone do with a 6502-based wire-wrap microprocessor demo board.  At least with modern microcontrollers you don't have to make 60-100 individual connections to make a simple working prototype computer demo board like you had to do 30-40 years ago.

The wires shown by the OP look more like logic analyzer probe wires, often having a round machined contact  (I have a bunch of these somewherez)....however, without an end photo, can't be sure

 

After some sleuthing I found this great-looking source.  These are machined contacts, not the flim-flam contacts that you use twice, then toss in the trash.

https://projectpoint.in/index.php?route=product/product&product_id=498119132852

adafriut has  some logic analyzer leads, that have this style on one end & the cheaper style ont the other (in a 10 or 16 pin block).

 

This jogged my memory, I bought about eighty or one hundred 36" micrograbber leads (Pomona or EZ-hook brand) on ebay for some ridiculous price (like $12 for the whole bunch)..it was such a great deal I bought without looking carefully...the other end was one of these heat-shrink machined contacts.  Now I need to remember where I put them!

Hi all,

 

Thanks for the answers, but please look at the OP with the image I attached.  These jumper wires are quite special, not the ones you recommended, which I already have.

 

Thanks!

Did you look at my posting #6

 

Here is similar...haven't found female on both ends....yet

I updated #6 with what appears to be the exact item you are looking for

There's not enough detail (resolution) or multiple views in #1 to really identify those.

I make my own with a crimped (soldered) connector and shrink tubing.  That's what they look like.

alieexpress has them, sparkfun, and probably every vendor you look at. In the Arduino age this has seem to have become a standard necessity and they should be very cheap, specially if you spend some time digging Alieexpress ( if you can affort to wait a bit for them to arrive.

No these are NOT the std Dupont square shape types....these are the rarer, possibly round, machine style contacts, such as used on logic analyzer probes.
