The latest addition to the Arduino family is here! The Arduino Leonardo is a microcontroller board based on the exciting USB-enabled ATmega32u4 (datasheet). This chip has about the same amount of flash, RAM, and capability as the ATmega328 found in the UNO. 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 spot for a 2.1mm power jack, an ICSP header breakout, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable to get started.
This version of the Leonardo does not come with any headers attached for an ultra-thin, lightweight Arduino!
The Leonardo differs from all preceding boards in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary chip (such as an FTDI friend, FTDI cable or the USB/Serial converter on the UNO). On one hand, this means that sketches on the Leo are a little bigger because it’s also handling USB interaction. On the other hand, it allows the Leonardo to appear on a connected computer as a mouse and/or 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.
This board is only supported in the latest Arduino IDE 1.0.1 so you will also need to update the IDE.
