The 4-Pin Female to Female Jumper Wire is designed for reliable signal and power connections between development boards, sensors, and modules. It features four parallel 70 cm wires terminated with standard 2.54 mm female connectors for compatibility with common headers used on Arduino, Raspberry Pi, and embedded systems. The extended cable length allows flexible positioning of peripherals and remote module connections during prototyping and testing. Suitable for breadboard projects, robotics, IoT systems, and educational electronics applications.
