Arduino Leonardo Pinout And Specification

About Arduino Leonardo

The Arduino Leonardo is a microcontroller board based on the ATmega32u4. It has 20 digital inputoutput 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.

20 digital IO pins on the Leonardo can be used as an input or output. They operate at 5 volts. The Arduino Leonardo digital pins can read only two states when there is a voltage signal present and when it is absent. This kind of input is usually known as digital or binary and these states are referred to as HIGH and LOW or 1 and 0. PWM pins

By connecting the Arduino Leonardo to the USB port of your PC with a USB cable, you can communicate between the Arduino Leonardo and your PC. Programs sketches created on the PC can be written to the Arduino Leonardo, and the Arduino Leonardo can be controlled from the PC via serial communication.

In this article we look at the Arduino Leonardo. Each of the 20 digital pins on the Leonardo can be used as an input or output. They are all 5 volt tolerant. TX TTL serial data using the ATmega32U4 hardware serial capability. On the Leonardo, the Serial class refers to USB CDC communication for TTL serial on pins 0 and 1, use the

The Leonardo was the first Arduino to use Atmel's ATmegaXU4 series chip with built-in USB. ATmega 32U4 Pin Mapping . The 20 digital io pins of the Leonardo can be used as input or output using the pinMode, digitalWrite, and digitalRead functions. Each operates at 5 V and can provide or receive a maximum of 40 mA.
