Male-to-Male Dupont Jumper Wire 40-Pin 40 cm | 400 mm Length 2.54mm Pitch Multi-Color Ribbon Cable for Breadboards, Arduino & Microcontrollers (Single Ribbon)

Description

The Male-to-Male Dupont Jumper Wire 40-Pin is an essential, highly flexible wiring ribbon engineered for solderless breadboarding, microcontroller prototyping, and circuit testing. Spanning an extended 40 cm (400 mm) in length, this 40-conductor multi-color ribbon features standard 1-pin male header pins molded onto both ends, allowing seamless interconnection between components without requiring any soldering.

Designed with a precise 2.54 mm (0.1 in) mil-spacing pitch compatibility, these wires mate securely with standard experimental breadboards, female pin headers, and development board sockets. The ribbon structure allows individual wires to be easily peeled apart or grouped into custom multi-wire harnesses, making it a versatile tool for working with Arduino, Raspberry Pi, Orange Pi, Banana Pi, and custom PCB projects.

Key Features

• Extended 40 cm Reach: Generous 400 mm length provides ample routing distance for larger breadboard layouts, multi-tier enclosures, and peripheral connections.
• Standard 2.54mm Pitch Compatibility: Molded male pin terminals are precisely spaced to mate securely with standard breadboard tie-points and female header sockets.
• Peelable Ribbon Construction: 40 parallel multi-colored wires can be kept together as a tidy ribbon or easily peeled off individually as needed.
• Durable & Reusable: High-quality crimps and resilient insulation withstand repeated plugging and unplugging cycles across active development work.
• Vibrant Color Coding: Multi-colored insulation simplifies wire tracing, power distribution, and multi-line debugging.

Benefits

• Solder-Free Efficiency: Eliminates the manual hassle of cutting, stripping, and bending hookup wire during circuit construction and debugging.
• Enhanced Prototyping Flexibility: Extra-long 40 cm reach bridges components across larger experimental setups where standard short jumpers fall short.
• Broad Ecosystem Compatibility: Universally compatible with Arduino, Raspberry Pi, Orange Pi, Banana Pi, and standard electronic test equipment.
• Reusable Interconnect: Precision-molded pins maintain firm contact pressure across extended operational use.
• Cost-Effective Harness: Bundles 40 individual male-to-male jumper lines into a single organized ribbon assembly.

Applications

• Breadboard Power & Signal Routing: Bridging power rails ($V_{cc}$ and GND) and digital/analog signals across experimental breadboard circuits.
• Microcontroller Interfacing: Connecting development boards (Arduino, Raspberry Pi, ESP32) to nearby sensor arrays, displays, and breakout modules.
• PCB & Motherboard Testing: Providing temporary or permanent signal links during hardware debugging and diagnostic testing phases.
• Educational Electronics: Simplifying wiring setups for students and hobbyists learning fundamental circuit design and digital communication.
• Custom Enclosure Wiring: Bridging internal control boards to modular peripheral units across extended chassis layouts.

Package Includes

• 1 x Male-to-Male Dupont Jumper Wire Ribbon (40 Pins, 40 cm Length)
