GenBasic GenBasic 80 Piece Female to Female 4 and 8 Inch Solderless Ribbon Dupont-Compatible Jumper Wires for Breadboard Prototyping

I needed the 4 inch to wire a Raspberry Pi to a miniature momentary switch so I can reset the Pi from the box without needing to remove the power cable. I put 2 pins on the reset contacts of the Pi and was going to cut the ends on the other side so I can solder the switch. Turns out that these will accommodate the thicker contacts of the switch so I did not need to use the solder iron and that saves time as I have to make quite a dew of these. I also have many other applications for them including peripheral devices that use the I2C interface for the Pi and Arduino.In any case, I like to have the 4" and the 8" in my jumper wires drawer because I never know when I am going to need a few and I like that I can just pill off a bundle of the amount of wires I need and use them in seconds.

It's cheap wire. Does its job making connections. Of the six wires in this pack I've used, one has a loose crimp and slides out of position easily. With how cheap the wire is, even if one in six are loose, I still feel I got my money's worth.

But the product option that comes with both sizes. It's the best value. Product is fine, it fits my esp32 pins and breadboard.

So I'm building an electronic clock from HeathKit - updated from the one I built in the 70s. And it calls for cutting a four-inch six wire ribbon, tinning the ends and soldering both ends to both the display and control boards. I did this once, and decided the next kit needs some ease in this step. Voila, the GenBasic 80 Piece male-male and female-female (4-inch & ~ 8-inch) not only were the right lengths, they also followed the standard color codes. Just Great!With an additional purchase of break-away PCB headers, these were the perfect fit - great utility, because troubleshooting is much easier, as may be needed.

Shipped extremely quickly and all of the wires came in perfect condition. I use these with both my ardiuno board and raspberry pi kits I recently bought and these work great when you want to quickly test something on the Pi's gpio headers without having to hook up the extension t to the bread board with the ribbon cables. Great purchase.
