Jumper Wires

Flexible pre-made wires for breadboard and module connections.

How it works

Jumper wires are short, flexible wires with connector ends for making temporary connections. They come in three end styles: male–male (pin on both ends, breadboard to breadboard), male–female (one pin, one socket, breadboard to module header pins), and female–female (sockets on both ends, module to module).

Wire color is purely for your own sanity — there's no electrical difference. The common convention is red for positive and black for ground.

Tips

  • Buy a kit with all three end types so you're never stuck.
  • Stick to red = +, black = GND to avoid wiring mistakes.
