Arduino Leonardo ( with headers) -1-152x152

Overview The Arduino Leonardo is a microcontroller board based on the ATmega32u4 ( datasheet) . It has 20 digital input/ output pins ( of which 7 can be used as PWM outputs and 12 as analog inputs) , a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. The Leonardo differs from all preceding boards in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Leonardo to appear to a connected computer as a mouse and keyboard, in addition to a virtual ( CDC) serial / COM port. It also has other implications for the behavior of the board; these are detailed on the getting started page.
