Proto Screw Shield V2 – Easy Connections and Prototyping for Your Arduino UNO R3

Expansion Board with Screw Terminals and Soldering Area for Stable and Solderless Connections

The Uno R3 Prototype Development Board – Proto Screw Shield V2 is an Arduino‑compatible expansion shield designed to make prototyping and wiring easier and more reliable for Arduino Uno R3 and compatible boards. This board combines screw terminal connectors with a prototyping area, allowing secure wiring and easy connection of sensors, modules, wires and custom circuits.

Key Features:

• Compatibility: Directly plugs into Arduino Uno R3 and compatible boards (e.g., Uno, Duemilanove).

• Screw Terminal Connectors: All main GPIO, analog, and power pins are broken out to screw terminals for secure, hassle‑free connections without soldering.

• Prototyping Area: Includes a central proto space with plated holes for soldering custom components, sensors or circuit sections directly on the shield.

• Full I/O Access: Exposes and breaks out all Arduino pins for easy attachment of shields, sensors, actuators or modules.

• Standard Form Factor: Compact design (~29 × 71 mm) matching the Uno R3 footprint.

• Stackable Headers: Allows additional shields to be stacked on top for expanded functionality.

Benefits:
✔ Transforms Arduino’s header pins into easy‐to‑use screw connections for robust wiring.
✔ Reduces reliance on messy jumper wires and breadboards.
✔ Great for quick development, testing and education.
✔ Useful for projects requiring frequent change of wiring or sensor layouts.

This shield is ideal for both beginners and experienced makers, giving a clean and reliable interface between Arduino and external electronics without complex wiring or additional adapters.
