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
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
