LilyPad Arduino 328 Main Board

The LilyPad Arduino 328 Main Board is a microcontroller, based on Arduino technology, specifically designed for integration into wearable projects and e-textiles. This lightweight, round board offers the same functionality as other Arduino boards but comes in a design that minimizes snagging and profile. It features large, sewable tabs that can be connected using conductive thread.

The board is built around an ATmega328 with the Arduino bootloader, with a minimal number of external components, keeping it small and simple. It operates from 2V to 5V and features large pin-out holes for easy sewing and connection. Each pin, except for (+) and (-), can control an attached input or output device, such as a light, motor, or switch.

The LilyPad technology, developed by Leah Buechley and SparkFun, is a unique solution for wearable e-textile applications. The boards feature large connecting pads for easy sewing into clothing. A variety of input, output, power, and sensor boards are available, and they're even washable!

A part of the sale proceeds goes back to Dr. Leah Buechley for the continued development and education of e-textiles and to Arduino LLC to help fund the development of new tools and IDE features.

The LilyPad Arduino 328 Main Board has a 50mm outer diameter and a thin 0.8mm PCB. Documentation and support material, including a schematic, Eagle Files, a LilyPad comparison guide, a datasheet for the ATmega328, LilyPad Arduino documentation, and GitHub resources, are available.
