The Proto-ScrewShield is a dual-purpose Arduino prototyping shield that combines a large through-hole prototyping area with screw terminal breakouts for every Arduino pin. Instead of soldering wires directly, you get sturdy, reliable screw terminals — making it easy to connect and disconnect external components without permanent joints.
The stackable "wing" design lets you slip this shield above or below virtually any other shield, so you never lose access to the Arduino's analog and digital pins. The R3 revision adds a stacking ICSP header and SCL/SDA breakouts for full compatibility with UNO R3, Mega, and Leonardo boards.
Key Features
- 36 Screw Terminal Breakouts – 3.5mm terminals for all Arduino pins, plus bonus GND and four free-use terminals
- Large Prototyping Area – 0.1" grid with power and ground rails
- High-Quality PCB – Selected for excellent resistance to repeated soldering and desoldering
- Stackable Design – Compatible above or below virtually any Arduino shield
- R3 Compatible – ICSP stacking header and SCL/SDA breakouts for UNO R3, Mega, and Leonardo
- Status LEDs – Diffused green power LED and a red user LED (ideal for pin 13)
- Reset Button – Onboard reset accessible from the shield
- Stacking Female Headers – Full set included for shield stacking
Ideal For
- Prototyping projects needing reliable, re-usable wire connections
- Connecting sensors, motors, and external components without soldering wires
- Arduino beginners building their first shield-based projects
Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- GND
- GND is the ground or reference connection (0 V) for a circuit. When connecting two devices together, their grounds must be joined so both agree on what counts as a low or high signal.
- Headers
- Rows of connector contacts on a fixed pitch (commonly 2.54 mm) used to link a board to a breadboard, jumper wires, or another board. They come as male pin headers and female socket headers; when a module ships with pre-soldered headers it can be used straight away, whereas bare pads require soldering the pins yourself.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
- Shield
- An add-on board that plugs into a main controller board to give it extra features such as sensing, motor control or communication. Knowing a product supports shields helps you judge whether it can connect neatly into an existing maker-board setup.
- through-hole
- A mounting style where the component leads pass through holes in a circuit board and are soldered on the other side. Through-hole parts are often easier to handle and solder by hand, which is useful for classroom and hobby projects.
