Italy original Arduino Leonardo development board A000052/57 microcontroller ATmega32u4

ATmega32U4

High-performance, low-power AVR 8-bit microcontroller.

Built-in USB communication

The ATmega32U4 has a built-in USB communication feature that allows the Micro to appear as a mouse/keyboard on your machine.

Battery connector

The Arduino Leonardo features a barrel plug connector that is ideal for use with standard 9V batteries.

EEPROM

The ATmega32U4 has a 1kb EEPROM that is not erased in the event of power failure.

Product introduction

Arduino Leonardo is a microcontroller board based on the ATmega32u4. It has 20 digital input/output pins (7 of which 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 connector, and a reset button. It contains everything you need to support a microcontroller; Simply connect it to your computer using a USB cable or power it with an AC-DC adapter or battery to get started.

What makes Leonardo different from all previous motherboards is that the ATmega32u4 has built-in USB communication and does not require a secondary processor. This allows Leonardo to appear as a mouse and keyboard ona connected computer in addition to a virtual (CDC) serial /COM port;

Arduino has been popular with Mak-er/STEAM maker education teachers, students, training institutions, engineers, artists, programmers and other enthusiasts since its release because of its open source, simple and easy to use, rich community resources and global technology iteration sharing.
