Female to Female Jumper Wire- 40pcs 20cm

Female to Female Jumper Wire- 40pcs 20cm

The Female to Female Jumper Wire- 40pcs 20cm ribbon pack is a fundamental prototyping component required for rapid circuit construction, diagnostic testing, and modular electronics assembly. Featuring a 40-pin parallel ribbon layout, this pack is fitted with standard 2.54 mm (0.1 inch) single-pin (1P-1P) female-to-female header sockets on both ends. This solderless interconnect solution allows engineers, students, and makers to cleanly separate the ribbon into individual strands or custom-width multi-pin wiring harnesses. It provides a quick, solder-free method to bridge discrete electrical nodes across various development environments.

Secure Socket Contact Mechanics and Data Integrity

Interconnecting modern embedded components demands reliable, low-resistance connections to protect sensitive logic transitions from data corruption. The Female to Female Dupont Cables feature internal high-strand copper-clad aluminum (CCA) cores insulated by soft, high-flexibility PVC. Each terminal housing contains a precision-engineered metallic leaf-spring socket. These sockets are designed to clamp onto standard 2.54mm square or round male pins found on circuit boards and test equipment, providing excellent retention that resists vibration-induced disconnects. This consistent physical contact ensures clean transmission for high-speed digital communication buses like I2C, SPI, and UART.

Key Features

• Professional-grade, 40-conductor prototyping ribbon cable with easily detachable individual strands.

• Symmetric dual-end terminations feature a structural 1-Pin Female to 1-Pin Female header profile.

• Natively compatible with standard $2.54\text{ mm}$ pitch male breakout pins, PCBs, and test benches.

• Chromatic 10-color repeating sequence simplifies complex multi-wire tracing and pin mapping.

• Solderless socket system allows for instant component swapping and high hardware reuse.

• Soft, low-memory PVC jackets resist kinking and insulation cracks inside tight project enclosures.

• Seamlessly bridges sensor modules directly to development boards without external breadboards.

• Generous 20cm length provides ample space for organized routing around crowded test setups.

Direct Peripheral Bridging and Development Ecosystem Synergy

In modern hardware design, many modules—such as I2C OLED displays, IMU gyroscopes, and ultrasonic rangefinders—come pre-assembled with integrated male header pins. Because this cable set features female connectors on both ends, it allows developers to plug these sensor boards directly into the male GPIO pin headers of single-board computers (SBCs) like the Raspberry Pi, Orange Pi, or Banana Pi, completely bypassing the need for a central breadboard. The repeating 10-color chromatic insulation scheme allows field technicians to easily color-code vital lines, such as mapping red for V CC, black for Ground (GND), yellow for Serial Clock (SCL), and blue for Serial Data (SDA).

Technical Reliability and Workshop Utility

Having a reliable supply of premium jumper cables eliminates time wasted troubleshooting intermittent data faults caused by low-grade wiring. The 20cm (approx. 7.87 inches) wire span balances clean, clutter-free bench organization with plenty of reach for articulated assemblies. Able to operate comfortably across standard hobbyist voltage domains ranging from low-power 1.8V logic up to high-draw 12V sensor lines, this reusable 40-piece wiring kit stands as an indispensable foundational asset for any electronics workshop, robotics lab, or automated industrial test fixture.
