Unique-Bargains 40P Male-Female Jumper Wire 2.54mm 22.5cm

40-Pin Male-to-Female Jumper Wire

This 40-pin male-to-female jumper wire uses a 2.54 mm pitch ribbon cable that separates easily for clean terminations with standard headers. The flat layout saves space and time on circuit interconnecting assemblies and is a popular choice for construction or repair work. It suits hobbyists, students and engineers building or debugging breadboard prototypes. The 22.5 cm length provides reach without excess slack on a typical workbench.

Passive Copper Cable Thermals

The cable is made of high-grade copper wire with a 1.3 mm diameter and carries only the current demanded by the connected circuit, so it generates no heat of its own and runs silently. No active cooling or power draw is associated with the wire itself. Normal use stays within the thermal limits of the copper conductor and the insulation. The passive nature means there are no fans, pumps or semiconductor junctions to consider.

Breadboard Build Integration

The ribbon terminates in standard 2.54 mm male and female headers that plug directly into breadboards, development boards or 40-pin GPIO strips such as those on Atmel AVR ISP programmers. The 225 mm by 60 mm overall footprint lies flat inside enclosures or across a bench, freeing vertical clearance for other components. Builders needing more than 40 conductors or a different pitch will require a separate cable assembly.
