Arduino Leonardo Development Board – ATmega32U4 USB Microcontroller for DIY Electronics and Robotics
KSh1,500.00
The Arduino Leonardo is a versatile microcontroller development board based on the ATmega32U4. With built-in USB communication, it can emulate a keyboard, mouse, or other USB device, making it ideal for automation, robotics, gaming controls, and DIY electronics projects.
📖 Product Description
The Arduino Leonardo is a powerful and flexible development board built around the ATmega32U4 microcontroller. Unlike many other Arduino boards, the Leonardo features native USB communication, allowing it to appear to a connected computer as a keyboard, mouse, joystick, MIDI device, or other USB peripheral without requiring additional hardware.
The board provides 20 digital input/output pins, of which 7 can be used as PWM outputs and 12 as analog inputs. It operates at 5V and runs at a clock speed of 16MHz, making it suitable for a wide variety of embedded and interactive projects.
The Arduino Leonardo is fully compatible with the Arduino IDE and supports thousands of existing Arduino libraries. It is commonly used in robotics, automation, custom USB controllers, sensor monitoring systems, gaming projects, and educational applications.
Because of its integrated USB capabilities, the Arduino Leonardo is especially popular for projects that require the board to simulate a computer keyboard or mouse, such as custom keypads, macro pads, automation tools, or interactive installations.
The board includes a micro USB connector for programming and power, a DC barrel jack or VIN pin for external power, and standard Arduino headers for connecting shields and modules.
