Dupont cables also known as jumper cables , jump leads, or Dupont wires —are affordable and versatile connectors used for prototyping and electronic projects. These cables are commonly used to link components such as sensors, Arduino boards, and breadboards. Jumper wires are small connectors used to easily link parts of a circuit. These cables are simple but essential for creating connections in electronic projects. Jumper wires are components in electronics that allow rapid and flexible connections between circuit elements without soldering. They constitute an indispensable tool for hobbyists working with Arduino and professionals who wish to prototype complex systems. Jumper wires reduce circuit design in two common forms: male-to-male, male-to-female, and female-to-female-which have different connection requirements. These are insulated copper, ensuring reliable conductivity and durability. Jumper ... Jumper wires are wires with connector pins at each end, used to connect two points without soldering. Learn about different types, colors and uses of jumper wires , and how to make your own.
