3.3V 8M Arduino Compatible LilyPad USB ATmega32U4 Development Board
Feature:
A microcontroller board based on the ATmega32u49 digital input\/output pins (of which 4 can be used as PWM outputs and 4 as analog inputs)An 8 MHz resonatorA micro USB connectionA JST connector for a 3.7V LiPo batteryA reset buttonContains everything needed to support the microcontrollerSimply connect it to a computer with a USB cable or power it with a battery to get startedATmega32u4 has built-in USB communication， eliminating the need for a separate USB-to-serial adapter. Which allows the LilyPad USB to appear to a connected computer as a mouse and keyboard， in addition to a virtual (CDC) serial \/ COM port.
