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

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

The DuPont 2.54mm male-to-male 1-pin jumper wire is the classic breadboard prototyping wire. With a male pin on both ends, it plugs directly into breadboard tie points, female headers, and female sockets — making it the standard choice for breadboard-to-breadboard wiring, component connections, and signal routing on prototyping boards.

Built to UL1007 PVC standards with 22AWG stranded copper, rated at 3A / 250V, and available in multiple colors for organized, error-free wiring.

Key Features

• Male-to-male configuration — plugs directly into breadboard tie points, female headers, and female sockets on both ends
• 2.54mm (0.1") pitch — universal standard for all breadboards, Arduino shields, and standard 0.1" female headers
• 22AWG stranded copper — flexible, low-resistance, handles repeated bending without fatigue
• 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 power (red), ground (black), and signal lines for instant identification

Typical Applications

• Breadboard-to-breadboard signal and power routing
• Connecting components (resistors, LEDs, capacitors) to breadboard power rails
• Arduino shield to breadboard wiring
• Connecting female-header modules to breadboard
• Custom single-wire harness assembly
• Test lead and probe extension wiring

Frequently Asked Questions

Q: What is the difference between M-M and M-F jumper wires?
A: Male-to-male wires connect two female sockets (e.g., breadboard-to-breadboard). Male-to-female wires extend a male pin to a female socket, ideal for GPIO-to-breadboard connections.

Q: Can I use M-M wires on a breadboard?
A: Yes. M-M wires are the standard breadboard jumper wire — both male pins insert directly into breadboard tie points.
