Female to Female Jumper Wires 40Pcs 20cm — DuPont Breadboard Cables These Female to Female jumper wires are the go-to cable for connecting male pin headers directly without a breadboard. Each pack contains 40 colour-coded DuPont cables, 20 cm (200 mm) in length, with a female socket on both ends. They are especially useful when working with GPIO pins on Raspberry Pi, Arduino, ESP32, and sensor modules that expose male headers. Key Specifications Type Female to Female (F2F) Quantity 40 pcs per pack Length 20 cm (200 mm) Pitch 2.54 mm (standard pin header spacing) Colours Assorted (40 different colours) Weight 30 g (per pack) Connector DuPont / 1P-1P What Are Female to Female Jumper Wires Used For? Female to Female jumper wires connect any two exposed male pins directly. They are most commonly used for: Connecting Raspberry Pi GPIO pins directly to sensors and modules Wiring Arduino male header pins to breakout boards and shields Linking ESP32 and NodeMCU boards to OLED displays, relay modules, and sensors Module-to-module connections where both ends have male headers Extending male pin connections that are too short to reach Compatible With Raspberry Pi GPIO (all models — 40-pin and 26-pin) Arduino Uno, Nano, Mega pin headers ESP32, ESP8266, NodeMCU, Orange Pi, Banana Pi DHT11/DHT22 temperature sensors, HC-SR04 ultrasonic sensors, relay modules Any component with 2.54 mm pitch male pin headers Why Choose These Jumper Wires?
