The 40-Pin Male-to-Male 20cm Jumper Wire Multicolor Ribbon Cable is a fundamental circuit prototyping component used to build temporary, solderless electrical connections. Also widely referred to as Dupont lines or breadboard jump cables, this set includes exactly 40 individual wires bonded together edge-to-edge as a neat ribbon strip. Each individual strand can be peeled away cleanly from the rest of the pack, allowing you to quickly route discrete signals or keep parallel data channels organized without cluttering your workspace.
✨ Key Features
- Completely Solderless Prototyping: Terminated with solid male pins on both ends, allowing immediate insertion into breadboards or female hardware headers.
- Easily Separable Ribbon Structure: The individual wires are bonded into a flat ribbon that can be peeled apart effortlessly into custom-sized wire groups.
- Chromating Rainbow Color Coding: Uses a continuous spectrum of contrasting colors to simplify loop diagnostics, trace paths, and avoid terminal wiring errors.
- Standard Industrial Pitch Size: Outfitted with a standard 2.54 mm (0.1 inch) terminal footprint that matches all mainstream development shields and development kits.
