Hey there, makers and tinkerers! Need some reliable jumper wires for your breadboard projects? This pack from sourcing map has you covered. You get three 40-pin female-to-female ribbon cables, each 50cm (about 19.7 inches) long. The pitch (that's the spacing between each wire) is the super common 2.54mm, so they'll plug right into standard breadboards, Arduino headers, Raspberry Pi GPIO pins, and most other development boards. They're made with copper wire for good conductivity. The best part? They're a flat ribbon cable, but you can easily separate out just the number of individual wires you need for a specific connection, which is super handy. Makes circuit prototyping, testing, and DIY electronics projects way faster and cleaner. The connectors are durable and should hold securely. A must-have basic for any electronics hobbyist's toolbox. Grab a pack and say goodbye to messy, tangled individual wires!
