The Arduino Leonardo is a microcontroller board powered by the ATmega32u4, featuring native USB 2.0 support for direct HID (Human Interface Device) emulation. With 20 digital I/O pins, 12 analog inputs, and 7 PWM outputs, it provides robust functionality for advanced embedded systems. Its 32 KB Flash memory (4 KB for bootloader), 2.5 KB SRAM, and 1 KB EEPROM enable efficient program execution. Operating at 5V with a 16 MHz clock, it supports USB serial communication without a separate chip, enhancing real-time applications like custom keyboards, automation, and interactive systems.
