The Prototype Shield V3.0 for Arduino Mega is a professional-grade prototyping platform designed for developers, electronics engineers, and hobbyists who need a flexible workspace for designing and testing custom circuits. This shield fits directly onto Arduino Mega boards and provides a large prototyping area along with an integrated 170-point mini breadboard, enabling both temporary and permanent circuit development.

Built with a high-quality gold-plated PCB for superior conductivity and durability, the shield supports through-hole components, SMD components via SOP28 footprint, and jumper-wire prototyping. It brings out all Arduino Mega I/O pins for easy access, allowing effortless integration of sensors, displays, communication modules, logic components, and custom interfaces.

Practical additions like onboard PWR and STAT LEDs, a reset button, and three mounting holes enhance usability and make the shield ideal for modular builds, enclosure installations, and long-term hardware projects.
