These are used in prototyping, installed as part of the circuit assembly, added after assembly to modify a circuit or added to correct a defect.<ref name="ctc">[http://www.circuitrework.com/guides/6-1.html 6.1 Jumper Wires], Circuit Technology Center</ref> == Use in prototyping == Jumper wires of insulated 26[[American wire gauge\|AWG]] wire terminated with [[crimping\|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.<ref>[https://www.rapidonline.com/jumper-wires-for-breadboard-arduino-raspberry-pi-olimex-etc-544268 Jumper Wires for Breadboard, Arduino, Raspberry Pi, Olimex, etc.], Rapid Electronics</ref> == Use in repair/modification == ''See [[Repairs]] and [[PCB repair]]'' == DuPont crimp connectors == A DuPont crimp consists of two parts, 0.1” (2.54mm) housing and separate metal crimp terminal. ~~Generally~~The AWG for ~~jump~~ wire ~~size is~~generally used, ~~with wire of~~is 22, 24, 26, or 28 or(standard 30ribbon ~~AWG~~cable) and a maximum diameter of 1.57mm.<ref>Molex data sheet [http://www.molex.com/webdocs/datasheets/pdf/en-us/0008500114_CRIMP_TERMINALS.pdf 08-50-0114]</ref><ref>Molex data sheet [http://www.molex.com/webdocs/datasheets/pdf/en-us/0008520072_CRIMP_TERMINALS.pdf 08-52-0072]</ref> Using the proper crimping tool makes a good crimp joint easy.
