Prototype Screw Terminal Block Shield Kit for Arduino Mega 2560 R3
This professional-grade prototyping shield is designed specifically for the Arduino Mega 2560 R3. It combines a large prototyping area with secure screw terminal blocks, allowing you to move your project from a fragile breadboard to a robust, permanent installation. The kit features high-quality FR-4 fiberglass and "stackable" headers, meaning you can still plug additional shields on top of this board. This is an unassembled kit; soldering is required.
Product Features
- Complete Terminal Access: Breaks out all 84 pins of the Arduino Mega to secure screw terminals for vibration-resistant wiring.
- Large Prototyping Area: Features a standard 2.54mm pitch grid for soldering custom sensors, ICs, and discrete components directly to the shield.
- Stackable Design: Includes long-pin female headers that pass through the PCB, allowing you to stack other Mega-compatible shields on top.
- High-Quality Construction: Dual copper layer FR-4 PCB with tinned pads for easy soldering and excellent conductivity.
- Flexible Mounting: Multiple mounting holes and terminal configurations allow for various installation methods in enclosures or control panels.

Assembly Guide
| Component | Installation Note |
|---|---|
| Female Headers | Solder these first. Ensure they are perfectly vertical so the shield aligns with the Arduino Mega pins. |
| Terminal Blocks | Group the 2-pole and 3-pole blocks to fill the outer perimeters. Ensure the wire entry holes face outward. |
| Prototyping Area | Use this space for permanent components like voltage regulators, level shifters, or pull-up resistors. |
