Stop fighting with loose connections! Our Female to Female (F-F) Jumper Wires (also known locally as Hole-to-Hole wires) are designed for reliable, click-in connections between modules. Whether youre linking an I2C LCD to an Arduino or an NRF24L01 to a Raspberry Pi, these Dupont-style cables ensure your signal stays clean. They come in a 40-pin rainbow ribbon that can be easily peeled apart into single wires or smaller groups to keep your project wiring neat and organized.
Universal Fit: Standard 2.54mm (0.1) pitch connectors compatible with almost all hobbyist electronics.
Rainbow Color Coding: 10 different colors make it easy to track which wire goes where (e.g., Red for VCC, Black for GND).
High Flexibility: Multi-strand copper wire allows for repeated bending without snapping.
Customizable: Easily peel off exactly the number of wires you need (1-pin, 4-pin for I2C, 8-pin for SPI, etc.).
