Specification:

Microcontroller: ATmega328P
Operating voltage: 2.7V ~ 5.5V (recommended 5V)
Input voltage: 2.7V ~ 5.5V (recommended 5V)
Digital I/O pins: 14 (of which 6 provide PWM output)
Analog input pins: 6
DC current per I/O pin: 40mA
Flash memory: 16KB (of which 2KB used by bootloader)
SRAM: 1KB
EEPROM: 512bytes
Clock speed: 16MHz

Note:

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

Package included:

1 x Arduino compatible LilyPad ATmega328P

• The Arduino Compatible 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 ATmega328 with the Arduino bootloader. The main board has a minimum number of external components to keep it as small (and as simple) as possible.
• The latest version supports automatic reset for even easier programming. The back side of the LilyPad is completely flat.
• It uses a surface mount programming connector, which keep the header from poking through.
