Description: These are two pin jumpers (also called shunts) that will create an electrical connection between two pin headers. Commonly used to modify settings on a board or device. Remember when you had to set an IDE hard drive as ‘Master’ or ‘Slave’ on the IDE ribbon? These jumpers were priceless if you sneezed and lost one.
Old ISA and 386/486 motherboards were famous for being packed with jumpers. Whenever throwing one away, I’d always pull the jumpers off. I must have hundreds of them. Good thing too, there’s no way I’d ever pay 35 cents for one. Why are these not 2 cents a piece? It’s not just SparkFun. I placed an order with Jameco. A transistor is .05 cents, but a jumper is .12? Go figure.
Especially when DFRobot sells them for $0.008 each, in a lot of 600. SparkFun could buy from them, sell them for less than they do now, still make a profit, and even carry them in six colors!
I just stole a pocket full of these from the stuff-that’s-not-used-anymore room at my dad’s office. :D
That’s awesome! Where does he work?
35cents for one… is that right? Can’t be, the gods must be crazy…
I know, that’s strange…
They say .35 cents but they show a quarter, that’s only .25 cents!
Don’t these silly SparkFun people know what a .35 cent piece looks like?
Wait, what? A quarter is NOT 25 100ths of a cent!
Quarter not included. (What a joke!)
For some reason, I never seem to have any of these when I need them.
