Description
Female-to-female jumper wires are flexible, insulated connecting leads with identical female connectors crimped on both ends. These wires are essential tools for prototyping and development work with breadboards, microcontroller boards, sensors, and modules. The female connectors are designed to fit snugly over standard 2.54mm (0.1-inch) pitch header pins, such as those found on Arduino Uno, ESP32, Raspberry Pi GPIO headers, and most breakout boards.
Key Features
- Female connectors on both ends for direct attachment to header pins, component leads, and breadboard jumper wires
- Flexible, insulated wire construction allows easy routing around other components and through tight spaces
- Standard 26 AWG (American Wire Gauge) conductor provides good current capacity while remaining flexible
- Color-coded insulation (typically black, red, brown, orange, yellow, green, blue, purple, gray, white) simplifies circuit identification and organization
- High-quality materials including tin-plated brass or beryllium copper connectors for reliable, corrosion-resistant connections
- Compatible with standard 2.54mm (0.1-inch) pitch headers, including male pin headers and breadboard spring clips
- Durable PVC insulation resists cracking and provides electrical safety up to typical operating temperatures
