A nice solid female connector on either end.
They have the flexibility of stranded wire but will fit directly onto male pin headers.
The only downside to the standard jumper wires we carry is that they're a tad too thin to use for most power applications, so we got some beefy ones!

These 20AWG jumper wires work just like our smaller gauge premium jumpers except that they can handle a little more juice.
If you've ever been unsettled by warm jumper wires, give these a try!
This pack contains ten jumpers with a female pin header on either side.
