Description
The items shown in your image are officially referred to as Female-to-Female (F-F) DuPont Jumper Wires.
These cables are the industry standard for electronics prototyping, designed to create temporary, solderless connections between components.

Common Applications
-
Prototyping: Connecting microcontrollers (Arduino, Raspberry Pi, ESP32) to sensors, displays, and modules.
-
Testing: Quickly bridging connections on a solderless breadboard.
-
Modular Wiring: Connecting components that have male header pins (e.g., servo motors, ultrasonic sensors, or LCD modules).
Important Usage Tips
-
Separation: These wires arrive as a “ribbon” connected together. You can easily pull them apart by hand to create single wires or smaller bundles (e.g., a 4-wire bundle for a motor driver).
-
Compatibility: These are designed to fit perfectly over male header pins (the thin, upright metal pins found on development boards).
-
Limitations: Because they rely on a friction-fit connection, they are best for prototyping. For permanent projects, soldering is recommended to ensure a vibration-resistant, long-term connection.
