40 Piece Male to Female 4 Inch Solderless Ribbon Dupont-Compatible Jumper Wires for Breadboard Prototyping

These are great things to have around if you are into building household projects using an Arduino like or Raspberry Pi like mini-processor. You can use them to prototype and/or for the final project. These are just wires with a male pin at one end and a female pin at the other. These are perfect for connecting a female header slot to a male pin on various sensor and actuator cards. I've also used them as "extension cords" when I just need more wire for my layout. The connectors have been pretty good.I bought one of these, a male to male and a female to female set of these connectors just to have around, and I've used a surprising number of them.

I needed an easy way to extend some wires for my retropie project converting some arcade 1up cabinets into multi game machines. Once I found these I was able to plug them on to the bus on the pi and then plug them into switches on the game console to control power and volume and extend the speaker wires. Nice thing was they made a good solid connection and I did not have to solder anything.

Great little pack of jumpers. Just what I needed. Have used better quality but these work just great and at a good price

Used these to make my own adapter cables.

Half of the male headers broke or got pushed in to itself on the first use. Some worked fine but most break.

Theses are great little jumpers, I used them to extend the reach from my track ball to my keyboard emulator on a stand up multi-cade I built.

Really needed this product for my step daughter’s science project at first I ordered a different one & it didn’t work so then I ordered this one & the project worked!

Excellent set. Only wish I had seen this sooner. If your doing bread board or working with Raspberry Pi or Ardunio I really recommend this set. The advantage here is the length. This makes prototyping easy!
