DuPont 2.54mm Male-to-Female 1-Pin Jumper Wire 22AWG UL1007 PVC

DuPont 2.54mm Male-to-Female 1-Pin Jumper Wire — 22AWG UL1007 PVC

The DuPont 2.54mm male-to-female 1-pin jumper wire is the most versatile single-conductor prototyping cable in any maker's toolkit. With a male pin on one end and a female socket on the other, it bridges pin headers to breadboards, extends GPIO pins, and connects modules to prototyping boards — all without soldering.

Built to UL1007 PVC standards with 22AWG stranded copper, rated at 3A / 250V, this wire handles both signal and low-current power lines reliably across thousands of insertion cycles.

Key Features

• Male-to-female configuration — the most versatile jumper type: extends pins, bridges headers to breadboards, connects modules to GPIO
• 2.54mm (0.1") pitch — universal standard for Arduino, Raspberry Pi, ESP32, STM32, and all standard pin headers
• 22AWG stranded copper — flexible, low-resistance, fatigue-resistant for repeated use
• UL1007 PVC insulation — rated −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, reliable multi-cycle connection
• Multiple colors available — color-code your wiring for instant identification

Typical Applications

• Extending Arduino or Raspberry Pi GPIO pins to breadboard
• Connecting sensor breakout boards (with female headers) to breadboard tie points
• Bridging module-to-module connections in prototyping rigs
• UART, I2C, SPI signal routing between boards
• LED, button, and relay module wiring
• Custom single-wire harness assembly

Frequently Asked Questions

Q: What is the difference between M-F and F-F jumper wires?
A: Male-to-female wires have a pin on one end and a socket on the other, making them ideal for extending pins or bridging a header to a breadboard. F-F wires connect two female headers directly.

Q: Is this compatible with Raspberry Pi GPIO?
A: Yes. The male end plugs into the Raspberry Pi 40-pin GPIO header, and the female end connects to a breadboard or sensor module.
