LilyPad Arduino 328P-AU Main Board


SKU: 000012 Category: Tags: , , , ,


The LilyPad Arduino 328P-AU Main Board is a specialized microcontroller board designed for e-textile and wearable electronics projects. It’s part of the LilyPad series developed by Arduino for creating soft, flexible, and sewable electronic prototypes. Here’s a description of its key features and functions:

**1. Microcontroller:** The LilyPad Arduino 328P-AU is based on the Atmega328P microcontroller, which is the same chip used in the classic Arduino Uno. This microcontroller is the heart of the LilyPad board and runs your program.

**2. Compact and Round Form Factor:** The board is circular, which makes it well-suited for wearables and e-textile projects. Its compact size and round shape allow for seamless integration into clothing and textiles.

**3. Sewable:** LilyPad boards are designed with large holes around the edges, which are meant for sewing conductive thread through, allowing you to attach components and sensors directly to fabric. This sewable nature makes it ideal for creating interactive clothing and accessories.

**4. Power Options:** The LilyPad board can be powered through a variety of sources, such as a coin cell battery, a LiPo (Lithium-Polymer) battery, or an external power supply. It includes a built-in power supply circuitry for efficient voltage regulation.

**5. Digital and Analog I/O Pins:** The board offers a selection of digital and analog input/output pins for connecting sensors, LEDs, and other components. These pins can be accessed by sewing or soldering connections.

**6. Program Upload:** You can upload your custom programs to the LilyPad Arduino board using the Arduino IDE and a suitable USB-to-Serial adapter. The board features a 6-pin programming header for this purpose.

**7. Integrated LED:** There is an onboard LED (typically red) that can be used for basic debugging or as an indicator in your projects.

**8. Low Power Consumption:** LilyPad Arduino boards are designed to be energy-efficient, which is crucial for wearables and battery-powered applications.

**9. Variety of LilyPad Sensors and Accessories:** The LilyPad ecosystem includes a range of sensors, modules, and accessories specifically designed to be sewn onto the board, making it easy to create custom wearable tech projects.

**10. Applications:** LilyPad boards are commonly used for creating interactive clothing, soft robotics, e-textiles, and other wearable electronics projects. They are popular in fashion technology, health monitoring, and artistic installations.

**11. Versatility:** While designed for wearables, LilyPad boards are also useful for non-wearable applications that benefit from a small, round, sewable form factor.

**12. Creative Expression:** LilyPad Arduino boards provide a platform for combining technology with artistic and creative expressions, making them popular among artists, designers, and makers.

The LilyPad Arduino 328P-AU Main Board is a versatile and unique platform for creating wearable electronics and e-textile projects. Its sewable design, combined with the power of the Arduino ecosystem, empowers makers and designers to bring their innovative ideas to life in the form of interactive, textile-based technology.
