40 Pin Female To Female Connector Jumper Wire

A 40-pin female-to-female wire is the same style of Dupont jumper ribbon as the male-to-male one, but with female sockets on both ends instead of pins.

Details

• Pin count: 40 wires joined together in a ribbon, detachable if you want single wires.

• Connector type: Female-to-Female (socket on both ends).

• Pitch: Standard 2.54 mm (fits Arduino headers, Raspberry Pi GPIO, sensor modules, breadboards with male pins, etc.).

• Length : 20 cm

  Colors: Commonly comes in rainbow/multicolor for easy tracing.

• Use cases:

  • Connecting male header pins on Arduino, Raspberry Pi, ESP32, or sensor modules together.

  • Extending connections between two modules with male headers.

  • Useful when both devices already have male pins soldered.
