Dupont 2.54mm Jumper Wire Connectors – Housings, Terminals & Pre-Crimped Cables
Dupont 2.54mm Jumper Wire Connectors – The Universal Prototyping & Wire Harness Standard
Yoeruyo's Dupont 2.54mm connector range covers the most widely used jumper wire and wire harness connector system in electronics prototyping, development, and production. The Dupont 2.54mm (0.1 inch) pitch connector — named after the original DuPont connector design — is universally compatible with Arduino pin headers, breadboard jumper wires, GPIO headers, and 2.54mm PCB pin headers worldwide. Our range includes single and dual-row housings, male and female crimp terminals, and pre-crimped jumper wire assemblies in a comprehensive selection of circuit counts and wire lengths.

Frequently Asked Questions
What is a Dupont connector?
The Dupont connector is a generic term for the 2.54mm pitch crimp connector system originally designed by DuPont and now universally adopted as the standard jumper wire connector for electronics prototyping. It is the connector used on virtually all Arduino jumper wire sets and breadboard-compatible development boards.
Are Dupont connectors compatible with Arduino pin headers?
Yes. Dupont 2.54mm female housings mate directly with the 2.54mm pin headers on Arduino Uno, Mega, Nano, Raspberry Pi GPIO, and all compatible development boards. This is the universal standard for prototyping jumper wire connections.
Can I crimp custom wire lengths?
Yes. Purchase Dupont housings and crimp terminals separately to make custom-length wire assemblies. A Dupont-compatible crimp tool (e.g., Engineer PA-09 or equivalent) is required for reliable crimps. Pre-crimped assemblies are also available in standard lengths.
What wire gauge is compatible?
Dupont 2.54mm crimp terminals accept wire from AWG 28 to AWG 22 (0.08mm² to 0.33mm²). AWG 26–24 is the most common gauge for jumper wire assemblies.
Do you offer bulk pricing for education kit and OEM suppliers?
Yes. Yoeruyo offers tiered pricing for orders of 500 units or more. Contact us for volume quotations, custom wire lengths, and OEM packaging options for kit assembly and production line integration.
