The 40-wires Female to Female Dupont Cable (20cm, 40P) is a versatile ribbon-style jumper wire bundle designed for rapid prototyping and permanent PCB connections. The bundle contains 40 individual wires, each terminated with female socket connectors on both ends. These female connectors are designed to plug directly onto male header pins with 2.54mm (0.1 inch) pitch – the standard spacing used on Arduino boards, Raspberry Pi GPIO, breadboards, and most development boards. The 20cm (approximately 7.87 inches) length provides sufficient reach between components without excessive slack, making it ideal for tidy project layouts. Each wire uses 28 AWG stranded copper conductor with PVC insulation for flexibility and durability. The rainbow color coding (different colors per wire) simplifies circuit identification and troubleshooting. This cable is especially useful for connecting devices with male pin headers (such as sensors, LCD displays, or microcontrollers) to other boards or to breadboards. The female-to-female configuration works with male pins on PCBs, Arduino shields, and sensor modules. No soldering is required – simply push the connectors onto the target pins for a secure friction fit.
