70cm Female-Female DuPont Jumper Wire 2/3/4 Pin 2PCS | 3D Printer Arduino Raspberry Pi Cable

70cm Female-Female DuPont Jumper Wire — 2/3/4 Pin, 2PCS

Extra-long 70cm female-female DuPont jumper wires for 3D printer wiring, Arduino sensor connections, and Raspberry Pi GPIO projects where standard 20cm jumper wires fall short. The 2.54mm pitch female-female connectors mate directly with Arduino headers, breadboard pins, and standard PCB connectors. Available in 2-pin, 3-pin, and 4-pin configurations to match your wiring needs.

Why 70cm?

• ✅ 3D printer wiring — long enough to route from control board to extruder, bed thermistor, or endstop switches
• ✅ Remote sensor connections — connect sensors mounted far from the Arduino or Raspberry Pi
• ✅ Cable management flexibility — route through cable chains and drag chains without tension
• ✅ Trimmable — cut to any shorter length if needed

Common Applications

• 3D printer endstop switch wiring (X/Y/Z axis)
• 3D printer thermistor and heated bed connections
• Arduino sensor module wiring (DHT22, ultrasonic, PIR)
• Raspberry Pi GPIO to remote sensor connections
• Breadboard-to-module extension cables
• CNC machine limit switch wiring
• Electronics lab and prototyping bench wiring

Package Contents

• 2× 70cm Female-Female DuPont Jumper Wire (pin count as selected)
