The Lilypad Arduino 328 Main Board is an Arduino-programmed microcontroller designed to be easily integrated into e-textiles and wearable projects. It offers the same functionality you find in other Arduino boards, in a lightweight, round package designed to minimize snagging and profile, with wide tabs that can be sewn down and connected with conductive thread.
Microcontroller: ATmega168 or ATmega328V
Operating Voltage: 2.7 – 5.5V
Input Voltage: 2.7 – 5.5V(Ensure to not exceed 5.5V and do not reverse the polarity)
Digital I/O pins: 14V
PWM Channels: 6
Analog Input Channels: 6
DC Current per I/O pin: 40mA
Flash memory: 16KB
EEPROM: 512 bytes
Clock Speed: 8MHz
It is used as a microcontroller board for wearables and in projects where light weight is required.
