#ARDUINO UNO PINOUT COMPARED TO MEGA SERIAL#

This allows it to appear as a mouse and keyboard, in addition to being recognized as a virtual (CDC) serial / COM port. The Leonardo 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. Plus, the ATmega32U4 offers built-in USB communication, eliminating the need for a secondary processor.

This board offers 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, microUSB connection, power jack, an ICSP header and a reset button. The Arduino Leonardo is built around the versatile ATmega32U4. 1.0 pinout: added SDA and SCL pins that are near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board.In addition, Revision 3 of the Uno offers the following new features: Instead, it features the ATmega16U2(ATmega8U2 up to version R2) programmed as a USB-to-serial converter. The Uno does not use the FTDI USB-to-serial driver chip. This popular board - based on the ATmega328 MCU - features 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, USB connection, power jack, an ICSP header and a reset button.
