Whadda WPM349 Multicolour Male-to-Male Jumper Wire Set, 65-Piece, 22 AWG, 110-240 mm

Prototyping electronics demands reliable, flexible connections, and this 65-piece jumper wire set delivers exactly that. Each wire features a male pin on both ends, ready to plug into standard 2.54 mm pitch breadboards, headers, and microcontroller boards like Arduino or Raspberry Pi. The assortment of eight colours—red, orange, yellow, green, blue, white, brown, and black—simplifies circuit tracing and organisation.

Advantages

Built from 22 AWG tinned copper with PVC insulation, these wires offer excellent conductivity and durability. The pre-cut lengths (45x 110 mm, 10x 160 mm, 5x 200 mm, 5x 240 mm) reduce clutter and save time compared to cutting your own. Flexible and reusable, they withstand repeated insertion and removal without losing spring tension, making them a staple for iterative prototyping.

Suitable for

• Breadboard circuit assembly and testing
• Connecting sensors, displays, and modules to development boards
• Educational electronics projects and STEM learning
• Rapid prototyping and proof-of-concept builds
• Repairing or extending existing jumper connections
