Leonardo R3 ATmega32u4 Development Board With Free USB Cable For DIY Starter For Arduino
Product Description:
The Leonardo Board is a microcontroller board based on the ATmega32u4 for Arduino. It has 20 digital input/output pins (of which 7 can be usedas 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.
