📝 Product Description:

The Arduino Leonardo R3 is a powerful microcontroller board based on the ATmega32u4, designed for beginners, hobbyists, and professionals in electronics and embedded systems. With 20 digital I/O pins (7 PWM outputs, 12 analog inputs), a 16 MHz crystal oscillator, micro USB connection, power jack, ICSP header, and reset button, it provides everything needed to start building projects instantly.

Unlike earlier Arduino boards, the Leonardo features native USB communication, eliminating the need for a secondary processor. This allows it to appear to your computer as a keyboard, mouse, and virtual serial COM port, making it ideal for DIY projects, automation, robotics, and human-computer interaction applications.

🔧 Key Features

  • ✅ Microcontroller: ATmega32u4

  • 🔌 Native USB Communication – Acts as keyboard, mouse, or virtual COM port

  • ⚡ 20 Digital I/O Pins – 7 PWM outputs & 12 analog inputs

  • 🖥 Crystal Oscillator: 16 MHz for stable performance

  • 🔋 Operating Voltage: 5V, Input 7–12V (recommended)

  • 🧰 Onboard Interfaces: Micro USB, power jack, ICSP header, reset button

  • 🏭 Compatible With: Arduino IDE & 100% Pro Micro compatible
