  • ATmega32U4 Microcontroller: Powered by the ATmega32U4 microcontroller running at 16 MHz, with 32KB of flash memory, 2.5KB SRAM, and 1KB EEPROM, providing ample resources for a wide range of projects.
  • USB HID Support: Unlike other Arduino boards, the Leonardo can emulate USB devices such as keyboards, mice, and game controllers, making it ideal for creating custom USB peripherals and human interface devices (HID).
  • 20 Digital I/O Pins & 12 Analog Inputs: Offers 20 digital I/O pins (7 of which can be used for PWM output), 12 analog inputs, and 4 hardware serial ports, enabling complex I/O-intensive applications.
  • Built-in USB Communication: Direct USB communication allows easy programming and allows the board to appear as a USB device, eliminating the need for an external USB-to-serial converter.
  • Fully Compatible with Arduino IDE: Seamlessly integrates with the Arduino IDE, providing access to a wide array of libraries, examples, and community-driven projects for rapid development and prototyping.
