SparkFun ProtoScrewShield _ws30 Stop Band Rejection: >30 dBThe 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 of 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.
