The Arduino Proto Shield is a versatile prototyping shield designed to facilitate the creation of custom circuits for various Arduino boards. This shield is ideal for users who need to test and develop their projects without the need for extensive soldering or complex setup.

Key Features:

• 1.0 Arduino Pinout: The shield features a standard Arduino pinout, ensuring compatibility with a wide range of Arduino boards, including Uno, Mega, and Leonardo.
• ICSP Connector: The shield includes an ICSP (In-Circuit Serial Programming) connector, which allows for easy programming and debugging of the Arduino board.
• Through Hole (TH) and Surface Mount Device (SMD) Footprints: The shield provides ample space for both TH and SMD ICs, making it suitable for a variety of component configurations.
• Power Lines and LEDs: The shield includes two power lines (IOREF and GND) and two LEDs pads, along with SPI signals breakout pads.
• SPI Signals Breakout Pads: These pads are designed for boards that have SPI signals only on the ICSP header, ensuring compatibility with various Arduino models.
• 24 Pin SMD Footprint: The SMD area is designed to accommodate up to 24 pins SOIC integrated circuits, providing ample space for complex SMD component configurations.

Technical Specifications:

• Dimensions: The maximum length and width of the Proto Shield PCB are 68.6 cm and 53.3 cm respectively.
• Weight: The weight of the shield is approximately 0.013 kg.
• Power Supply: The shield brings power from the Arduino standard IOREF and GND pins to the two power bus rows, usable for powering DIP sockets or other components independently of the chosen board voltage (3.3V or 5V).
• SPI Connection: Only 5V, GND, and RST are wired to the respective pins on the header. MOSI and MISO are present only on the connector pads.

Usage and Compatibility:

The Arduino Proto Shield is designed to be fully stackable and compatible with various Arduino boards, including Uno, Mega, and Leonardo. It is ideal for prototyping custom shields and can be used in a wide range of projects, from simple sensor connections to complex circuit designs.

Documentation and Support:

The Arduino Proto Shield is open-source hardware, allowing users to build their own boards using the provided EAGLE files and schematics. For any technical issues or project-related queries, users can refer to the Arduino Forum or contact customer support.
