Official Arduino Leonardo R3 Development Board with Headers
The Official Arduino Leonardo R3 Development Board is a microcontroller board compatible with Arduino, based on the ATmega32U4. It features native USB communication, allowing it to act as a keyboard, mouse, or other Human Interface Device (HID) without the need for a separate USB-to-serial converter. With pre-soldered headers, the board is easy to use for prototyping, education, and DIY electronics projects.
Features:
- Compatible with Arduino Leonardo R3 architecture.
- Based on ATmega32U4 microcontroller with native USB support.
- Can emulate USB keyboard, mouse, and other HID devices.
- Pre-soldered headers for easy and secure connections.
- No external USB-to-serial converter required.
- Fully compatible with Arduino IDE and existing libraries.
- Suitable for robotics, automation, HID projects, and learning purposes.
Specifications:
- Board Type: Microcontroller Development Board
- Microcontroller: ATmega32U4
- Operating Voltage: 5V
- Input Voltage: 7–12V (recommended)
- Clock Speed: 16 MHz
- Digital I/O Pins: 20
- PWM Pins: 7
- Analog Input Pins: 12
- Flash Memory: 32 KB (4 KB used by bootloader)
- SRAM: 2.5 KB
- EEPROM: 1 KB
- USB Interface: Micro USB
- Form Factor: Leonardo R3
- Applications: HID devices, robotics, automation, embedded systems
Package Includes:
