Choosing a LilyPad Arduino for Your Project

LilyPad Arduino USB - ATmega32U4 Board

Features:

• 5 Digital I/O pins
• 4 Analog pins
• ATMega32U4
• Built-in ON/OFF switch
• Built-in power supply socket (JST connector) for a 3.7v LiPo battery and charging circuit (no additional battery charger needed)
• Simplified layout with less pins, giving more space for sewing or less complex projects
• Micro USB connection instead of FTDI header pins

The LilyPad Arduino USB is similar to the LilyPad Arduino Simple Board, but uses a different chip - the ATMega32U4, which has built-in USB support. If the FTDI header pins on other LilyPad Arduinos feel too bulky or FTDI Boards are often lost or misplaced, this board is a great alternative.

Note: the digital I/O pin layout is slightly different than the LilyPad Arduino Simple - the USB uses pins 2 and 3 instead of 5 and 6.
