Lilypad Arduino Simple

The LilyPad Arduino Simple is designed for e-textiles and wearables projects. It can be sewn to fabric and similarly mounted power supplies, sensors and actuators with conductive thread.


Unlike the LilyPad Arduino Main Board, the LilyPad Simple has only 9 pins for input/output. Additionally, it has a JST connector and a built in charging circuit for Lithium Polymer batteries. The board is based on the ATmega328.

The LilyPad Arduino Simple was designed and developed by Leah Buechley and SparkFun Electronics.

You can find your board warranty information here.

Getting Started

In the Getting Started section, you can find all the information you need to configure your board, use the Arduino Software (IDE), and start to tinker with coding and electronics. SparkFun Electronics has a range of accessories for use with the LilyPad Arduinos.
