DuPont connection Jumper Wires – 20 cm / 40-Way Bundle (M-M)

This set of DuPont jumper wires is designed for quick connections on breadboards, between pin headers on PCBs, or for creating neat wiring bundles. The bundle includes a 40-wire rainbow ribbon with a length of approximately 20 cm, equipped with M-M (male-to-male) connectors.

The wires are arranged in a ribbon format, allowing you to separate individual wires as needed or keep them together for cleaner wiring. With a standard 2.54 mm (0.1") pitch, they are compatible with most Arduino, Raspberry Pi, and other microcontroller development boards.

Why choose this DuPont jumper wire bundle?

Ideal for checking and testing electronic circuits. Suitable for laboratory use, DIY projects, servicing, and connecting modules, sensors, and development boards.

40-wire bundle in rainbow ribbon format
Length: approximately 20 cm
