ELEGOO 120pcs Dupont jumper wires 20cm

These 120 multicoloured Dupont jumper wires provide a neat, flexible way to link breadboards, sensors and modules in hobby electronics and prototyping. Each cable measures 20cm and can be separated from the ribbon to match odd‑spaced headers, so you can craft exactly the harness you need without excess cable or fiddly extensions.

Highlights

The kit groups 40‑pin male‑to‑female, 40‑pin male‑to‑male and 40‑pin female‑to‑female ribbons so you have common connector types ready for Arduino projects and small microcontroller builds. The colour coding helps keep signal, power and ground runs identifiable at a glance, which reduces wiring mistakes during iterative testing.

Usage tips

These jumpers suit quick breadboard layouts, temporary test rigs and classroom exercises. If you need a permanent connection, consider soldering once the circuit is final, as the friction fit is best for prototyping. It’s a good fit if you value tidy wiring and fast reconfiguration during development. You may want to skip it if you require shielded or high current cabling.

Care & maintenance

Store the ribbons loosely coiled to avoid kinking and keep contacts dust‑free by covering when not in use. Regular visual checks will spot bent pins or loose crimps early, and replacing individual wires is simple thanks to the separable ribbon design.

The kit is a practical, low‑cost accessory for makers, students and anyone assembling or debugging breadboard circuits. According to the product details, the wires are manufactured to be durable for repeated insertion and removal, and the mix of connector types covers the majority of common prototyping needs.
