Product Description

Overview

The LilyPad 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) or the ATmega328V.

Summary

Warning: Don’t power the LilyPad 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 can be programmed with the software. *Note*, the LilyPad 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 LilyPad comes preburned with a bootloader that allows you to upload new code to it with the software. You can also bypass the bootloader and program the ATmega through the ICSP (In-Circuit Serial Programming) header; seethese instructions for details.

Power

The LilyPad can be powered via the USB connection or with an external power supply.

If an external power supply is used, it should provide between 2.7 and 5.5 volts. This can come either from an AC-to-DC adapter (wall-wart) or battery. Again, don’t power the LilyPad with more than 5.5 volts, or plug the power in backwards: you’ll kill it.

Physical Characteristics:

The LilyPad is a circle, approximately 50mm (2″) in diameter. The board itself is .8mm (1/32″) thick (approximately 3mm (1/8″) where electronics are attached).

Washability:

Wash at your own risk – we do ;). We recommend washing projects by hand with a mild detergent. Drip dry. Make sure you remove your power supply first!
