Final answer:
The LilyPad is the board that is designed to be sewn into clothing, thanks to its conductive pads and flat back, making it suitable for wearable e-textile projects.
Step-by-step explanation:
Which Board is Designed for Wearable Projects?
The question refers to various platforms that can be used for electronic projects and specifically asks which one can be sewn into clothing. Among the options provided, the LilyPad is the board that is designed specifically for use in e-textiles and wearable projects. The LilyPad is a microcontroller board that is designed with large conductive pads and a flat back to allow it to be easily sewn into clothing with conductive thread. This design makes it perfect for integrating electronics into fabrics and wearable creations, enabling designers and hobbyists to create interactive garments. On the other hand, the UNO, RedBoard, and Mega are more commonly used for prototyping on breadboards or PCBs and are not specifically tailored for sewing into textiles. The LilyPad's unique design has led to its adoption in educational institutions and it has become a favorite tool among designers and artists working at the intersection of fashion and technology.
