Tired of messy, tangled wiring? These 20cm Male-to-Female (M-F) Jumper Wires are the ultimate bridge between your microcontrollers, sensors, and breadboards. Delivered as a convenient 40-pin rainbow ribbon cable, they easily peel apart into individual wires or custom-sized multi-wire buses (like 4-pin or 8-pin strips) to keep your project looking exceptionally neat and organized.

Each wire is fitted with a standard, high-quality male header pin on one end and a sturdy female socket on the other. With a generous 20cm (roughly 8 inches) of flexible, PVC-insulated length, they offer the perfect balance of reach and neatness—long enough to route around larger modules, but short enough to avoid signal degradation and excessive wire clutter on your workbench.

Key Features

• Peel-to-Size Ribbon: Comes as a unified 40-pin ribbon cable. Simply peel off exactly what you need—whether it is a single wire, a 4-pin bundle for an I2C sensor, or an 8-pin strip for an LCD display.

• Vibrant Color-Coding: Ten distinct, repeating colors make it incredibly easy to trace connections from your sensor back to your microcontroller, reducing wiring mistakes.

• Standard 2.54mm (0.1″) Pitch: 100% compatible with standard breadboards, Arduino, Raspberry Pi, ESP32 development boards, and male pin headers.

• Secure, Snug Fit: Precision-molded connectors ensure a firm, reliable connection that won’t easily slip loose during mobile robot tests or high-vibration projects.
