A ribbon cable connects the pin sockets of an Arduino USB 2 Serial micro to a breadboard and wire jumpers make interconnections on the breadboard.

A jumper wire also known as jumper link, jumper, jump wire or DuPont cable is a connecting wire, bare at the ends or terminated with some type of connector.

Use in prototyping

Jumper wires of insulated 26AWG wire terminated with crimped pins or sockets in plastic housing are used to make connections between pin headers or sockets. With 2.5 mm (0.1 inch) housing they're suitable for interfacing single board computers like the Arduino and Raspberry Pi. These will also fit without damage to interconnect the components on solderless breadboard although here 22 AWG solid-core hookup wire with bare ends can be used instead.[1]

DuPont crimp connectors

A DuPont crimp consists of two parts, a housing and metal crimp terminal. The terminals are bought separately. Generally for jump wires 0.1” (2.54mm) size is used, with wire of 22, 24, 26, 28 or 30 AWG and a maximum diameter of 1.57mm.[2] For 0.156" use wire of 18, 20, 22 or 24 AWG, with a maximum diameter of 2.79mm.[3]

Using the proper crimping tool makes a good crimp joint easy. A properly crimped joint does not need soldering and is more than strong enough.[4] Most crimp terminals are designed to be crimped, not soldered. Soldering a crimped terminal may weaken the mechanical connection, reduce electrical conductivity, and damage the terminal. As a general rule, you should not solder a crimp terminal.[5]
