20cm 40 Pin Male to Male Arduino Jumper Wires 2.54mm

Part Number	20cm 40 Pin Male to Male Arduino Jumper Wires 2.54mm
Description	The 20cm 40 Pin Male to Male Jumper Wires provide a simple and reusable way to make temporary electrical connections during electronics development, testing and prototyping. Each wire has a male pin connector at both ends, making the set suitable for connecting compatible female headers, breadboards, development boards, sensors and electronic modules. This set contains 40 multicolor jumper wires arranged as a flexible ribbon. Individual wires can be separated from the ribbon when required, allowing you to use a single jumper or keep several wires together for cleaner circuit connections. This ribbon-and-separable design is also commonly found in current 40-wire jumper products sold in Pakistan. Each jumper wire is approximately 20cm (200mm) long, providing convenient reach between components while keeping breadboard and prototype circuits manageable. The connectors are designed for commonly used 2.54mm pitch headers, making these Dupont-style jumper wires useful with a wide range of electronics hardware. Comparable Pakistani 20cm male-to-male sets are likewise specified for 2.54mm headers.
