Male to Male Jumper Wires 40 Pin

Build and test circuits faster with this Male to Male Jumper Wires 40 Pin cable set, a must-have for every electronics workbench. The pack contains 40 individual male-to-male Dupont jumper leads supplied as a flexible ribbon strip. Each wire has a single male pin connector on both ends, allowing easy plug-in connection between breadboards, development boards, sensors, display modules, relay boards and PCBs fitted with standard 2.54 mm pin headers. These jumper wires are designed for solderless prototyping. Simply insert one end into a breadboard row or female header socket and connect the other end to another module, controller board or test point. The 2.54 mm spacing makes them compatible with the most common Arduino UNO/Nano/Mega headers, Raspberry Pi GPIO breakout boards, ESP8266/ESP32 modules, motor driver boards, sensor modules and general-purpose PCB headers. The cable strip can be peeled apart into single wires or kept in groups for neat signal harnesses such as SPI, I2C, UART, power and ground connections. With a typical 20 cm length and flexible insulated wire construction, these male to male jumper cables are convenient for compact breadboard layouts as well as quick diagnostic wiring. They are suitable for low-voltage electronics, digital logic signals and low-current prototype circuits. The colour-coded wires help trace connections easily, reducing wiring mistakes during project development, classroom experiments and product testing. Common applications include Arduino sensor interfacing, Raspberry Pi GPIO experiments, breadboard circuits, robotics prototypes, IoT projects, electronics repair testing and PCB-to-module interconnections. The box/pack includes one 40-pin strip of male-to-male jumper wires. Pin note: both ends are male Dupont-style pins, so they are intended for breadboards, female headers and jumper sockets; choose male-to-female or female-to-female jumpers if your project uses different connector types.
