The next generation Proto-ScrewShield is a dual-purpose prototyping shield. Now only does it have a large 0.1" grid prototyping area but it also extends the Arduino pins to sturdy, secure, and dependable screw terminal blocks. You even get a few bonus terminals for extra GND and four 'free' terminals for whatever connections you wish!
The stack-able wing design allows you slip this under any shield and still get easy access to the "analog" & "digital" ports of the Arduino. The ScrewShield can be stacked above or below pretty much every other shield.

• 1 large high-quality US-made PCB, specifically chosen for its excellent resistance to lots of soldering and desoldering (essential for prototyping boards)
• Plenty of prototyping space, with power/ground rails
• Diffused green power LED, extra diffused red LED for user choice (although we suggest to connect it to pin 13)
• Reset button
• 2 sets of 6-pin stacky female header pins
• 2 sets of 8-pin stacky female header pins
• Lots of 3.5mm terminal blocks to fill 36 breakouts on the board
  

Comes as a kit of all through-hole parts. You'll need to assemble the kit using a soldering iron, diagonal cutters and solder but its an easy kit and should take less than half an hour. For more information, instructions, and tips check out the Screwshield page.
