Overview

The LilyPad Arduino is a microcontroller board designed for wearables and e-textiles. It can be sewn to fabric and similarly mounted power supplies, sensors and actuators with conductive thread. The board is based on the ATmega168V (the low-power version of the ATmega168) (datasheet) or the ATmega328V (datasheet). The LilyPad Arduino was designed and developed by Leah Buechley and SparkFun Electronics.

Summary

Warning: Don't power the LilyPad Arduino with more than 5.5 volts, or plug the power in backwards: you'll kill it.


Microcontroller ATmega168V or ATmega328V

Operating Voltage 2.7-5.5 V

Input Voltage 2.7-5.5 V

Digital I/O Pins 14 (of which 6 provide PWM output)

Analog Input Pins 6

DC Current per I/O Pin 40 mA

Flash Memory 16 KB (of which 2 KB used by bootloader)

SRAM 1 KB

EEPROM 512 bytes

Clock Speed 8 MHz

Programming

The LilyPad Arduino can be programmed with the Arduino software (download). *Note*, the LilyPad Arduino should only be programmed with software versions 0010 or higher. You can program it with earlier versions, but all of the time related functions will be off (twice as slow as they should be).

The ATmega168V or ATmega328V on the Arduino LilyPad comes preburned with a bootloader that allows you to upload new code to it with the Arduino software. You can also bypass the bootloader and program the ATmega through the ICSP (In-Circuit Serial Programming) header; see these instructions for details.
