Screw Shields V2 Terminal Expansion Board | Secure I/O & Power Breakout for Arduino Uno R3
Description
The SPIDER Automation Screw Shields V2 Terminal Expansion Board is an essential hardware accessory engineered to enhance connection integrity for Arduino-based projects and industrial prototypes. By replacing traditional, unreliable breadboard wiring with heavy-duty screw terminals, this expansion shield ensures that every digital, analog, and power pin is locked down securely against accidental disconnections and mechanical vibrations.
Designed with a stackable pass-thru header layout, the Screw Shield V2 allows you to easily interface external sensors, actuators, and power supplies directly while retaining the ability to layer additional shields on top. It streamlines complex wiring harnesses, making control panels and automation test benches clean, organized, and structurally reliable.
Key Features
- Dedicated I/O Screw Terminals: Provides secure screw-clamp connections for all microcontroller signal and power lines.
- Stackable Pass-Thru Design: Features integrated pin headers enabling multi-shield stacking and modular expansion.
- Optimized Compatibility: Fully tailored for Arduino Uno R3 and standard Arduino Uno hardware layouts.
- Direct Plug-in Installation: Mounts cleanly onto the host microcontroller without requiring soldering or special tools.
- Compact Form Factor: Precision-dimensioned footprint (66 × 19 × 16 mm) fits neatly inside standard enclosures.
Benefits
- Eliminates Loose Wiring: Screw-down terminals prevent intermittent connection faults caused by loose jumper wires.
- Enhanced System Reliability: Industrial-grade clamping mechanism ensures steady electrical contact in active environments.
- Modular Flexibility: Allows simultaneous connection of sensors and peripheral modules while keeping stacking options open.
-
Clean Enclosure Layout: Replaces messy prototype wiring with structured, professional terminal routing.
Applications
- Industrial Prototyping & Control Racks: Secure signal termination for custom Arduino-based automation controllers.
- Sensor Data Acquisition Benches: Stable wiring interface for multi-sensor environmental or industrial monitoring setups.
- Educational & R&D Laboratories: Durable test rig component for student and engineer development workstations.
-
Permanent Microcontroller Deployments: Secures field wiring in fixed-installation embedded electronics projects.
