Jumper Wire Set (M-M, M-F, F-F, 40-pin each)

Build, test and modify circuits faster with this complete Jumper Wire Set for breadboard and embedded electronics prototyping. The kit combines all three popular Dupont jumper cable styles: male-to-male for breadboard-to-breadboard or breadboard-to-header links, male-to-female for connecting development boards to modules, and female-to-female for joining two header-pin modules without soldering. With 40 wires of each type, this 120pcs assortment is suitable for electronics labs, robotics clubs, Arduino projects, Raspberry Pi GPIO experiments and everyday repair benches. Each jumper is designed for standard 2.54mm Dupont-style headers commonly found on Arduino compatible boards, Raspberry Pi expansion boards, sensor modules, relay modules, motor driver modules and solderless breadboards. The wires are color-coded so power, ground and signal lines can be identified easily while debugging. The 40-pin ribbon format can be separated into individual wires or smaller groups, allowing clean custom connections instead of messy loose wiring. This set is especially useful when you frequently change circuits during learning, prototyping or testing. Use male-to-male wires for MB102-style solderless breadboards, male-to-female wires for breadboard-to-sensor connections, and female-to-female wires for module-to-module GPIO wiring. The approximate 20cm length offers a practical balance between reach and tidy layout on a desk or project base. Package includes 1 x 40-pin male-to-male jumper wire strip, 1 x 40-pin male-to-female jumper wire strip and 1 x 40-pin female-to-female jumper wire strip. These are low-voltage prototyping cables intended for signals and small electronics connections; they are not a substitute for high-current power wiring.
