Reliable connections are the foundation of any successful electronics project. When building Arduino-based automation systems, custom IoT devices, or complex robotics, standard short wires often fall short. This 30cm 40-Pin Dupont Jumper Wire Ribbon Cable provides the essential extra length required for chassis-mounted components and spaced-out microcontrollers.

Engineered with a high-grade copper core and flexible PVC insulation, these cables endure repeated plugging and unplugging without fraying or losing signal integrity. The 40 individual wires come attached in a neat, color-coded flat ribbon. This intelligent design keeps your workspace perfectly organized, while allowing you to effortlessly peel apart customized sets (such as a 3-pin cable for a servo motor or a 4-pin cable for an I2C module) exactly when you need them.

Available in all three essential configurations—Male to Male, Female to Female, and Male to Female—these jumper wires feature standard 2.54mm pitch connectors that grip tightly onto breadboard holes and microcontroller header pins. Sourced directly for engineers, hobbyists, and professionals, this prototyping gear is available locally through QKZee Technologies for immediate deployment in your next build.

40 Pin Jumper Wires 30cm – Male to Male, Female to Female & Male to Female

Make your electronics prototyping and wiring easier with this 40 Pin Jumper Wire Set, 30cm length, designed for Arduino, ESP32, Raspberry Pi, breadboards, sensors, modules, and other electronic development boards.

These Dupont jumper wires are available in three commonly used connector configurations:

• Male to Male (M-M)
• Female to Female (F-F)
• Male to Female (M-F)

With a 30cm wire length, these jumper cables provide enough flexibility for breadboard circuits, sensor connections, development boards, and DIY electronics projects without creating unnecessary cable clutter.

The wires are especially useful for Arduino projects, ESP32 projects, Raspberry Pi projects, robotics, IoT systems, STEM projects, electronic prototyping, and educational experiments.
