DuPont 2.54mm Female-to-Female 1-Pin Jumper Wire — 22AWG UL1007 PVC
The DuPont 2.54mm female-to-female 1-pin jumper wire is the essential single-conductor prototyping cable for Arduino, Raspberry Pi, and breadboard projects. With a standard 0.1" (2.54mm) pitch female connector on each end, it plugs directly into pin headers, GPIO pins, and breadboard tie points without adapters or tools.
Built to UL1007 PVC insulation standards with 22AWG stranded copper, this wire delivers reliable signal and power connections rated at 3A / 250V — more than sufficient for all standard microcontroller and sensor applications.
Key Features
- Female-to-female configuration — connects pin headers to pin headers, GPIO to breadboard, sensor to module
- 2.54mm (0.1") pitch — universal standard compatible with Arduino, Raspberry Pi, ESP32, STM32, and all standard pin headers
- 22AWG stranded copper conductor — flexible, low-resistance, handles repeated bending without fatigue
- UL1007 PVC insulation — rated for −25°C to +80°C, flame-retardant, RoHS compliant
- 3A / 250V rating — suitable for power and signal lines in all standard prototyping applications
- Tin-plated brass contacts — corrosion-resistant, low insertion force, reliable multi-cycle connection
- Available in multiple colors — use color coding to organize power, ground, signal, and data lines
Typical Applications
- Arduino UNO / Nano / Mega GPIO wiring
- Raspberry Pi 40-pin GPIO connections
- ESP32 / ESP8266 sensor and module wiring
- Breadboard-to-breadboard signal routing
- Sensor breakout board connections (I2C, SPI, UART)
- LED, button, and switch wiring in prototyping circuits
- Custom single-wire harness assembly
