New! As of June 23, 2014 we now have an R3 update to this design – we now have a stacking header for the ICSP 2×3 pins and breakout the SCL and SDA pins. It now works much better with R3 UNO’s, Mega, Leonardo, as well as stacking nicely with any shield.
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 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)
Full set of stacking female header pins
Lots of 3.5mm terminal blocks to fill 36 breakouts on the board
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
