Jumper Wires Male/Female 40 Conductor × 4″ (10cm)
Male-to-female jumper wires — 40 conductors × 10cm (4″), color-coded for easy circuit identification. Connect Arduino GPIO pins directly to breadboard tie-points, or extend male header pins to female socket modules. Essential for Arduino sensor wiring and Raspberry Pi GPIO projects.
Key Specifications
- Type: Male / Female (M-F) | Conductors: 40
- Length: 10cm (4″) | Wire gauge: 28AWG
- Insulation: Flexible PVC | Color-coded: Yes (40 colors)
- Pitch: 2.54mm | Compliance: RoHS compliant
Typical Applications
- Arduino GPIO pin to breadboard connections
- Raspberry Pi GPIO to sensor module wiring
- Extending male header pins to female socket modules
- Servo, sensor and display module wiring
