The key difference is built-in USB communication, allowing the Leonardo to appear as a keyboard, mouse, or serial device to a connected computer — no secondary USB chip required. With 20 digital I/O pins, 12 analog inputs, 7 PWM channels, and a micro USB connection, the Leonardo is ready for interactive projects straight out of the box. This version comes with all headers pre-soldered for easy breadboard and shield use. Key Features Native USB – Built-in USB on the ATmega32U4 enables keyboard, mouse, and serial device emulation Pre-Soldered Headers – Ready for immediate use with breadboards and compatible shields 20 Digital I/O Pins – 7 usable as PWM outputs, with 40mA per pin 12 Analog Inputs – 10-bit resolution on pins A0–A11 Multiple Power Options – Micro USB, DC power jack (7–12V), or VIN pin header Specifications Microcontroller – ATmega32U4 Operating Voltage – 5V Input Voltage – 7–12V recommended (6–20V limits) Interface – Micro USB Digital I/O Pins – 20 PWM Channels – 7 Analog Input Channels – 12 DC Current per I/O Pin – 40mA DC Current for 3.3V Pin – 50mA Flash Memory – 32KB (4KB used by bootloader) SRAM – 2.5KB EEPROM – 1KB Clock Speed – 16MHz Board Dimensions – 70 × 55 × 14 mm (2.76 × 2.17 × 0.55 in) Note: The Leonardo differs from the Arduino Uno in its USB handling and is best suited for users with some Arduino experience. Requires Arduino IDE 1.0.1 or higher.
