Arduino Lilypad

The Arduino Lilypad is not your typical microcontroller board. It’s designed specifically for wearable electronics, making it perfect for projects that involve integrating technology into clothing and accessories. Unlike traditional Arduino boards, the Lilypad is sewable and washable, allowing you to embed it seamlessly into fabric.

The Arduino LilyPad Board is predicated on the ATmega168V (the low-power version of the ATmega168) or the ATmega328V.

With its compact size and flexibility, the Lilypad opens up a world of creative possibilities for makers, designers, and tech enthusiasts alike. Whether you’re looking to create interactive garments, smart textiles, or sensor-based accessories – the Arduino Lilypad has got you covered.

This versatile board contains everything you need to bring your wearable tech ideas to life. From LED lights to sensors like accelerometers and temperature sensors, the Lilypad offers a wide range of components that can be easily connected to create personalized projects tailored to your specific needs.

This board was designed and developed by Leah Buechley and SparkFun electronics.

This board has 14 digitals I/O pins and 6 analog pins.
