SparkFun DEV-09729 ProtoScrewShield
The ScrewShield extends all pins of the Arduino out to 3.5mm pitch screw terminals. It also has a lot of the utility provided by Arduino Protoshield, including: a large prototyping space of both connected and unconnected 0.1" spaced through-holes, a couple 5V and GND busses, a reset button, general use push button, and a 5mm yellow LED.
This product includes all the parts shown and comes in kit form and must be soldered together by the end user.
Note: This product is a collaboration with Tod Kurt, John Edgar Park, and Brian Jepson of WingShield Industries and a portion of each sale goes to them for product support and continued development.
