The Arduino LilyPad ATmega328P Compatible Board is a lightweight, sewable microcontroller board specially designed for wearable electronics and e-textile projects. Based on the ATmega328P microcontroller, the LilyPad combines the flexibility of the Arduino platform with a unique circular design featuring large conductive sew tabs that can be stitched directly onto fabric using conductive thread.

Operating at 8MHz and a voltage range of 2.7V to 5.5V, the LilyPad is optimized for low-power battery-operated applications. It supports the Arduino IDE and can be programmed using an FTDI-compatible USB-to-Serial programmer. The board includes digital I/O, analog inputs, PWM outputs, UART, SPI, and I²C communication, making it suitable for interactive clothing, smart textiles, wearable sensors, LED displays, soft robotics, and educational STEM projects.

Its thin PCB, compact size, and washable design (after removing the power source) make the LilyPad an excellent choice for fashion technology, cosplay, wearable health monitoring, and creative electronic textile applications.
