These premium female-female jumper wires are handy for making wire harnesses or jumpering between headers on PCBs. They're 200mm (~7.8") long and come loose as a pack of 40 (10 pieces of red, blue, yellow, and Adafruit black). They have 0.1" female header contacts on either end and fit cleanly next to each other on standard-pitch 0.1" (2.54mm) header. 

These jumper wires are a little more expensive than most because they use silicone covered wires, they're a little more durable and they're more heat-resistant than standard PVC covered wires.

We have tons of different Jumper Wires available, in all shapes and sizes!

For best results, when plugging these into a male header, have the sides with the 'silver latch bit' sticking out since that side is a tiny bit wider than 0.1".

Please Note: The length of the jumper wires is sometimes a bit longer than what is listed.
