Arduino Mega Proto Shield

Arduino Mega Proto Shield

The Arduino Mega Proto Shield is a blank prototyping expansion board designed to stack directly onto the Arduino Mega 2560. It provides a generous solderable breadboard area along with all Mega pin headers broken out, giving you a permanent platform to build and integrate custom circuits directly onto your Arduino Mega.

Key Features

• Large Prototyping Area — solderable through-hole grid for building permanent custom circuits
• Full Pin Breakout — all Arduino Mega digital, analog, power, and communication pins accessible via headers
• Mini Breadboard Compatible — fits a standard 170-point mini breadboard (not included) for rapid prototyping
• Reset Button — onboard reset button passed through from the Mega
• Power Rails — dedicated VCC and GND rails across the prototyping area
• Direct Mega Stack — standard shield form factor, plugs directly onto Arduino Mega 2560
• ICSP Header — ICSP pins broken out for SPI and direct programming access

Technical Specifications

• Compatible Board: Arduino Mega 2560
• Prototyping Grid: Through-hole, 2.54mm pitch
• Operating Voltage: 5V (via host board)
• Pin Headers: All Mega pins (digital, analog, power, ICSP)
• Mini Breadboard Slot: Yes (breadboard not included)
• PCB Color: Green (may vary by batch)

Ideal For

Perfect for engineers and makers who want to build permanent add-on circuits for their Arduino Mega — custom sensor interfaces, relay drivers, voltage dividers, or any circuit that graduates beyond a temporary breadboard setup.

No soldering skills required for breadboard use. Soldering recommended for permanent circuit assembly.
