ProtoShield for Arduino – Build Permanent Projects with Easy Access to All Pins

Expansion Board with Soldering Pads, Power Filters and Space for Your Components

The 328 ProtoShield Prototype Expansion Board Geekcreit for Arduino is a prototype expansion shield designed for Arduino boards based on the ATmega328P microcontroller (such as Arduino UNO or Duemilanove). It provides a convenient platform to quickly build, test and solder custom circuits directly onto your Arduino controller, making it ideal for prototyping, learning and electronics experimentation.

Key Features:

• Compatibility: Works with Arduino boards using the ATmega328P footprint (UNO/2009 compatible).

• Prototype Area: Large prototyping zone with 0.1" hole spacing ideal for soldering components and building custom circuits.

• Mini Breadboard Included: Often includes a small breadboard that attaches to the shield for quick, solder‑free testing before soldering.

• Extended Pin Access: Breaks out Arduino’s I/O and power pins for easy connection to sensors, modules and other hardware.

• Prototyping Convenience: Great for hobby electronics, education, sensor testing and rapid prototyping right on the Arduino board.

By directly stacking on your Arduino, this proto shield helps maintain solid electrical connections during development and testing — ideal for creating reliable prototypes and experimenting with circuit designs.
