SPIDER Automation Raspberry Pi Proto Screw Shield | 40-Pin Terminal & Prototyping Shield
Description
The SPIDER Automation Raspberry Pi Proto Screw Shield is the ultimate industrial breakout board designed to bridge single-board computers with real-world field wiring. By combining a full set of secure 3.5mm pitch screw terminal blocks with a versatile prototyping shield, this board eliminates unreliable jumper connections, making it ideal for robust panel mounts, industrial enclosures, and permanent multi-sensor deployments.
Pre-assembled for immediate installation, the shield maps all 40 Raspberry Pi GPIO, power, and ground pins directly to secure terminal blocks. The integrated double-sided PCB prototyping grid features interconnected and isolated 0.1-inch spaced through-holes, giving developers ample workspace to add custom discrete components, pull-up resistors, conditioning circuits, or custom signal filtering networks.
Key Features
- Full 40-Pin GPIO Breakout: Comprehensive terminal block mapping for all Raspberry Pi 3 and 4B interface signals.
- Secure 3.5mm Screw Terminals: High-quality terminal blocks offering firm clamping force to prevent wire dislodgement under vibration.
- Dual-Sided Prototyping Area: Etched through-hole grid with plated vias allowing clean component soldering on both sides.
- Pre-Assembled Industrial Build: Factory-assembled hardware delivered ready for immediate mechanical mounting and deployment.
- Breadboard Compatibility Space: Central region designed to support small adhesive breadboards for rapid temporary circuit testing.
- Optimized Trace Routing: Low-resistance copper traces ensuring clean signal transmission across all digital and analog lines.
- Robust Mechanical Stability: Rigid PCB substrate engineered to withstand repeated screw-down torque and handling stress.
- Compact Form Factor: Precision dimensions matching standard Raspberry Pi HAT footprints for clean enclosure fitting.
- Enhanced Maintenance Access: Simplifies multimeter probing and signal tracing during system debugging and maintenance.
Benefits
- Ensures Secure Electrical Connections: Screw terminals lock wires tightly, preventing accidental disconnection in high-vibration industrial environments.
- Accelerates Circuit Prototyping: Combines connection blocks and custom soldering grids on a single unified board layout.
- Simplifies Field Maintenance: Allows individual wires to be swapped or tested without soldering or rewiring entire pin headers.
- Protects GPIO Header Pins: Reduces mechanical wear and tear on the native Raspberry Pi board pins through dedicated breakout connections.
- Streamlines Panel Enclosure Wiring: Provides a clean, organized termination point for multi-cable wiring harnesses.
Applications
- Industrial Automation Control Panels: Interfacing factory sensors, limit switches, and control relays with single-board computers.
- Custom IoT Gateway Nodes: Deploying multi-sensor data loggers in permanent, secure enclosures.
- Robotics & Mechatronics Prototyping: Terminating motor driver signals, encoders, and feedback loops securely.
- Laboratory Test Rigs: Building dedicated experimental setups requiring frequent wiring adjustments.
- Smart Building Automation: Managing environmental monitoring sensors, access control units, and lighting triggers.
