Screw Shield for Arduino Development Boards

The screw terminals are spaced perfectly for stacking on an Uno, and being able to swap sensors without touching a soldering iron is a huge time-saver for quick prototypes. I've already used it on two different boards and the pins fit snug every time.

Finally got tired of soldering headers for every project — this board just plugs straight into the Arduino's female headers and gives you solid screw terminals. I've already used it to connect six different sensors and everything held firm without a single loose wire.

Putting this on my Leonardo was a breeze - the silkscreen labels for each terminal made wiring up six sensors without soldering so much faster than my old breadboard setup.
