Screw Shield V2 Stud Terminal Expansion Board (Double Support) for Arduino UNO R3
The Screw Shield V2 is a robust terminal expansion solution designed for the Arduino UNO R3, UNO, and Duemilanove boards. This “double support” expansion board provides a highly reliable interface that converts all standard I/O and power pins into secure screw terminal blocks, eliminating the instability of traditional breadboard wiring and jumper cables.
This shield is an ideal solution for creating permanent, industrial-grade projects where secure, durable connections are paramount. Its stackable design means it can be combined with other shields, making it versatile for both complex business applications and individual DIY projects.
Description
Free your Arduino projects from the shackles of loose jumper wires and unreliable connections. The Screw Shield V2 is an essential tool for any maker, educator, or engineer looking to “harden” their prototype into a reliable, field-deployable system.
This V2 version improves on earlier designs by breaking out all I/O interfaces from the Arduino controller into labeled screw terminals on both sides of the board. This thoughtful “double support” design ensures easy access to every pin even when the shield is integrated into an enclosure or stacked with other expansion boards.
The board features dedicated power (5V, 3.3V) and ground (GND) rails extended alongside the signal pins, which simplifies wiring for sensors, servos, and other modules. Constructed from high-quality, durable materials, the Screw Shield V2 is built to last, suitable for a wide operating temperature range (-40℃ to +85℃), and ready for demanding applications. The direct plug-in design requires no soldering to assemble, making setup quick and convenient.
Features
  • Secure Screw Terminals: Provides robust, reliable, and secure screw-down connections for all digital I/O (D0-D13) and analog input (A0-A5) pins.
  • “Double Support” Design: I/O pins are broken out to terminals on both the left and right sides of the board for improved accessibility and organization.
  • Stackable Compatibility: Retains the original expansion board sockets, allowing other shields to be stacked on top using stacking headers.
  • Power Distribution Rails: Includes onboard 5V, 3.3V, and GND rails running alongside the signal pins for organized power distribution.
  • No Soldering Required: This is a direct plug-and-play shield that eliminates the need for soldering.
  • Wide Operating Range: Durable construction suitable for diverse environments with an operating temperature range of -40°C to +85°C.
  • Clear Pin Labels: All pins are clearly silk-screened with labels for quick and easy identification.
  • Compatibility: Fully compatible with Arduino UNO R3, Arduino UNO, and Duemilanove boards.
Usage
The Screw Shield V2 streamlines the process of connecting external components to an Arduino board for various applications:
  1. Industrial/Commercial Control: Use the secure terminals to wire switches, sensors, solenoids, and other components for reliable, permanent installations in robust environments.
  2. Robotics & Motion Control: Connect motor drivers, servos, and power sources with a strong physical connection that won’t vibrate loose during operation.
  3. Educational Setups: Provides a durable platform for classroom experiments where circuits are frequently handled and reconfigured, reducing connection failures common with breadboards.
  4. Permanent DIY Projects: Transition home automation, weather station, or monitoring system prototypes into stable, long-term devices by securing all wiring.
To use the shield, simply plug it into the headers of your Arduino UNO R3. Use a small screwdriver to clamp the stripped ends of wires securely into the clearly labeled terminal blocks.
Q: Is soldering required to use the Screw Shield V2?

No, this V2 shield is designed for direct plug-and-play use. The terminal blocks and headers are pre-assembled, and connections are made using a small precision screwdriver to secure the wires.

Q: How does the "Double Support" design help?

The “double support” refers to breaking out the pins to screw terminals on both the top-left and top-right edges of the board. This allows you to route wires more cleanly and access pins even if another shield is stacked above it.

Q: Can I stack other Arduino shields on top of the V2?

Yes. The V2 design retains all original Arduino pin sockets, and most versions come with female stacking headers, allowing you to stack additional shields on top without losing the terminal connections.

Q: Is this compatible with my Arduino Mega 2560?

Yes, the Screw Shield V2 is compatible with the Arduino Mega 2560, as it shares the standard R3 pin layout form factor for the main I/O headers.

Q: What is the maximum current rating I can safely draw from the terminals?

While the general I/O pins are limited by the Arduino’s microcontroller (around 16mA per pin), the power terminals (5V, 3.3V, Vin, GND) can typically handle higher currents, often up to 10A in total for the power buses, though specific ratings can vary by manufacturer. Always verify the current limits of your specific Arduino board and project needs.
