Want to stack more than one shield at a time? Use these instead of standard 6-pin headers to add extra functionality to your shield!
Arduino is cool. Shields are cool. More shields are more cool.
And what makes it easy to stack shields? These do! Our FPin6L-413. Catchy name, right?
It's a female socket strip, 6 positions long, with a Long modification of 0.0413" tail. See?
In short, you solder these in where the standard Arduino Shield interface pins would go, but now you also have a matching set of female sockets on top! Use them for stacking more shields, or just as convenient test-measurement points for your probes.
