Arduino Mega Proto Shield Rev3 (PCB)

The Arduino Mega Proto Shield Rev3 is a prototyping board designed for the Arduino Mega 2560 standard pinout. It provides a dedicated area for soldering through-hole and surface-mount components, making it easy to build custom circuits as a single stackable module.

The shield features extra connections for all Arduino Mega I/O pins, a reset button, an ICSP connector, and power bus rows for convenient wiring. Use it with a small solderless breadboard (not included) for rapid prototyping, or solder your components directly for a permanent build.

Key Features

• Mega-Compatible Pinout – 1.0 Arduino pinout with full access to all Mega I/O pins
• Prototyping Area – Multiple through-hole pads at 100 mil pitch for custom circuits
• SMD Footprint – 14-pin SMD footprint at 50 mil pitch for surface-mount ICs
• 32 Double-Row Pads – Standard Arduino breakout layout
• Power Bus Rows – 5V and GND rails between through-hole footprints
• Reset Button – Convenient access to board reset
• ICSP Connector – 5V, GND, and RST wired; MOSI and MISO on connector pads
• Open-Source Hardware – Schematics and Eagle files freely available
