Proto Screw Shield V1.0 – Pre-Assembled Terminal Block Expansion Board for Arduino UNO R3 – Red Color
The Proto Screw Shield V1.0 is a highly versatile and robust expansion board designed for the Arduino UNO R3 platform. This pre-assembled board efficiently breaks out all Arduino I/O pins to secure screw terminals, simultaneously offering a substantial prototyping area for custom components. It provides a professional, reliable interface for connecting external wiring without the hassle of loose jumper wires or extensive soldering during initial setup.
This shield in Red Color is an excellent fit for hobbyists seeking a clean, permanent installation, and for businesses requiring durable, easily maintainable interfaces for industrial or commercial control systems.
Description
Elevate your Arduino projects from breadboard chaos to organized reliability with the Proto Screw Shield V1.0. This board addresses common frustrations associated with intermittent jumper wire connections by providing secure, high-quality screw terminals for every single I/O pin (Digital, Analog, Power, GND).
The shield is designed with efficiency and longevity in mind. It features a generous, double-sided prototyping grid with standard 0.1″ (2.54mm) spacing, allowing you to build semi-permanent custom circuits directly on the PCB. The robust design and plated-through holes can withstand repeated soldering and modifications.
For ease of use, the shield incorporates a convenient, on-board reset button and an LED pre-wired to Digital Pin 13 for debugging and status indication. The package includes stacking female headers, ensuring the board is stackable so you can add additional shields while still having full access to all screw terminals. Whether you are creating a complex sensor network in a lab or a simple home automation system, the Proto Screw Shield V1.0 provides the stability and accessibility needed for reliable circuit development and long-term deployment.
Features
  • Secure Connectivity: Reliable screw terminal blocks (typically 3.5mm or 3.81mm pitch) for all Arduino I/O pins, ensuring durable connections.
  • Prototyping Area: Large, double-sided prototyping space with standard 0.1″ (2.54mm) grid for integrating custom through-hole components.
  • Stackable Design: Includes female headers allowing for the integration of other Arduino shields on top of this one.
  • On-board Indicators: Integrated Power-On LED and a user-accessible LED connected to digital pin 13.
  • Easy Access Reset: A dedicated reset button for convenience, mirroring the function of the main Arduino board’s reset button.
  • Durable Construction: Built with high-quality FR4 PCB material in a distinct Red finish.
  • Wide Compatibility: Designed for use with Arduino UNO R3, Leonardo, Mega, Due, and other compatible boards.
Usage
The Proto Screw Shield V1.0 serves as a critical interface for enhancing the connectivity and durability of Arduino projects:
  1. Industrial Automation: Provides a professional way to connect robust, shielded wires from industrial sensors, relays, and PLCs to the Arduino controller.
  2. Permanent Installations: Ideal for projects that move beyond the breadboard phase and require a permanent, reliable wiring solution in a fixed location or enclosure.
  3. Custom Circuit Integration: The prototyping area enables the creation of custom sensor interfaces or driver circuits that are seamlessly integrated onto a single shield.
  4. Educational and DIY: Simplifies the process of wiring complex projects, ensuring secure connections that are less prone to accidentally disconnecting, which is common with standard jumper wires.
Simply attach the shield to your Arduino board headers. A small flathead screwdriver is used to clamp bare wire ends securely into the terminal blocks.
Q: Is the red color purely aesthetic, or does it signify a different function?

The color (red in this case) is purely an aesthetic preference and does not change the functionality or technical parameters of the standard Proto Screw Shield V1.0 design.

Q: Is this shield fully assembled, or do I need to solder the terminal blocks on myself?

This product listing specifies a pre-assembled version. All headers and terminal blocks are factory-soldered and ready to use right out of the box.

Q: What is the biggest advantage of using screw terminals over a breadboard?

Screw terminals provide mechanically secure connections that will not easily pull out, making them much more reliable for permanent, mobile, or vibration-prone installations compared to temporary breadboard jumper wires.

Q: Can I use this with an ESP32 or Raspberry Pi?

This shield is specifically designed to match the form factor and pin mapping of the Arduino UNO R3. It is not directly compatible with non-Arduino platforms like the Raspberry Pi or most ESP32 development boards.

Q: What type of wire should I use with these terminals?

You can use standard solid or stranded core wire, typically within the 26 AWG to 16 AWG range. For stranded wire, using wire ferrules can provide an even more secure and clean connection.
