A000052, Arduino Leonardo Development Kit Platform based on the ATmega32U4 8-bit AVR RISC MCU

A000052, Arduino Leonardo Development Board based on the ATmega32U4 8-bit AVR RISC MCU. It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16MHz 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 board 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
