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
Specifications
- Compatible Board – Arduino Mega 2560
- PCB Size – 101.5 × 53.3 mm (2.7 × 2.1 in)
- Weight – 13g
Ideal For
- Building custom permanent circuits for the Arduino Mega
- Rapid prototyping with a breadboard overlay
- Consolidating project wiring into a single stackable shield

Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.
- GND
- GND is the ground or reference connection (0 V) for a circuit. When connecting two devices together, their grounds must be joined so both agree on what counts as a low or high signal.
- ICSP connector
- An In-Circuit Serial Programming connector is a header used to reprogram a microcontroller directly with a programmer. It matters if you want advanced control, bootloader recovery, or to program the board without using the normal USB method.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
- RST
- RST (reset) is a control pin used to restart or reinitialise a device to a known state. Connecting an RST pin to a microcontroller lets the host reset the device, which can help with reliable start-up or recovery.
- Shield
- An add-on board that plugs into a main controller board to give it extra features such as sensing, motor control or communication. Knowing a product supports shields helps you judge whether it can connect neatly into an existing maker-board setup.
- SMD
- SMD means surface-mount device, a component style designed to be soldered directly onto the surface of a circuit board rather than through holes. SMD parts are compact and mounted flat on the board, which suits smaller and mass-produced designs.
- solderless breadboard
- A reusable board with rows of internally connected holes for building circuits by pushing in components and jumper wires, with no soldering required. It lets you prototype and rewire a circuit quickly and reversibly before committing to a permanent, soldered build.
- through-hole
- A mounting style where the component leads pass through holes in a circuit board and are soldered on the other side. Through-hole parts are often easier to handle and solder by hand, which is useful for classroom and hobby projects.
