20cm Female to Female Jumper Wire

Female-to-female jumper wires solve a different wiring case than the male-to-male kind: connecting two components that both already have pin headers, without a breadboard in between. That covers module-to-microcontroller wiring directly onto GPIO header pins, or linking two boards that both expose male header pins, both common once a project moves off the breadboard toward its final wiring.

At 20cm, there is enough slack to route around a small enclosure or between boards mounted a short distance apart, and the flexible PVC-insulated copper core keeps its connection reliable through repeated plugging and unplugging during development.

Standard wiring stock for connecting sensor modules, displays and other header-equipped boards directly to a microcontroller's GPIO pins without an intermediate breadboard.
