40 Pin Male-to-Male Dupont Jumper Wire Set

This 40 Pin Male-to-Male Dupont Jumper Wire Set is a standard interconnect cable pack used for quick electronics prototyping and circuit testing. The set includes 40 individual multi-colour jumper leads joined as a ribbon, allowing users to separate the required number of wires for a project. Each cable is approximately 20 cm long and has male Dupont pins on both ends, making it suitable for connecting breadboards, Arduino boards, Raspberry Pi GPIO headers, sensor modules, development boards and PCB pin headers with 2.54 mm spacing. These jumper wires are useful for temporary test connections, educational kits, lab work, hobby electronics and embedded development where solderless wiring is required. The flexible Dupont format helps reduce setup time and makes it easy to rearrange circuits during debugging or prototyping. It is a commonly used accessory for makers, students, repair technicians and electronics developers working with standard header-based modules.
