10Cm Hole To Hole Jumper Wire Dupont Line 40 Pin Arduino Jumper Wire also named as female to female jumper wire is very useful while prototyping electronics circuit.

However A jump wire (also known as jumper, jumper wire, jumper cable, DuPont wire, or DuPont cable – named for one manufacturer of them) is an electrical wire or group of them in a cable with a connector or pin at each end (or sometimes without them – simply “tinned”)

Moreover which is normally use to interconnect the components of a breadboard. Other prototype or test circuit, internally or with other equipment or components, without soldering.

Individual jump wires are fitted by inserting their “end connectors” into the slots provided in a breadboard, the header connector of a circuit board, or a piece of test equipment.

Features:

1. 100% brand new and high quality Multicolored 40-pin Breadboard Jumper Wires Ribbon Cables. 
2. Although this Include one 40-pin female to female jumper wires.
3. The female ends meant for insertion into standard 0.1 quot;(2.54mm)
4. The cables can be separate to form an assembly containing the number of wires you require for your connection and also to support non-standard odd-spaced headers. 
5. Portable design, easy and safe to use.
