3.3V 8M Arduino Compatible LilyPad USB ATmega32U4 Development Board.
A microcontroller board based on the ATmega32u4 that contains everything needed to support the microcontroller. This includes an 8 MHz resonator, micro USB connector. JST connector for a 3.7 LiPo battery and a reset button. 9 digital input/output pins (of which 4 can be used as PWM outputs and 4 as analog inputs) are available.
Simply connect it to a computer with a USB cable or power it with a battery to get started. The ATmega32u4 has built-in USB communication, eliminating the need for a separate USB-to-serial adapter. This allows the LilyPad USB to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port.
