DescriptionThe "Leonardo R3" is an Arduino-compatible development board based on the ATmega32U4 microcontroller. It is part of the Arduino family and offers several unique features compared to some other Arduino boards.
Here are the key details about the Leonardo R3 board:ATmega32U4 Microcontroller: The Leonardo R3 board is built around the ATmega32U4 microcontroller. This 8-bit microcontroller operates at 5V and has 32KB of flash memory, 2.5KB of SRAM, and 1KB of EEPROM. It is known for its built-in USB support, which allows it to act as a USB device, making it suitable for USB HID (Human Interface Device) applications.
Micro-USB Connector: The board features a micro-USB connector as its primary interface for connecting to a computer or power source. The micro-USB port is used for both power supply and USB communication with the microcontroller.
Compact Form Factor: The Leonardo R3 is designed with a compact form factor, making it suitable for a wide range of embedded systems and projects, including those with space constraints.
Built-in USB Functionality: One of the standout features of the Leonardo R3 is its native USB connectivity. It can emulate a USB keyboard, mouse, or other HID devices, allowing for seamless interaction with a computer. This feature is particularly useful for projects involving input devices, game controllers, and automation.
GPIO Pins: The board provides a set of GPIO (General Purpose Input/Output) pins, including digital pins, analog pins, and power pins. These pins allow you to connect various sensors, actuators, and other electronic components to the board.
Compatibility with Arduino IDE:The Leonardo R3 is fully compatible with the Arduino IDE. You can write and upload Arduino sketches to the board, utilizing the extensive collection of Arduino libraries and code examples.
Programming Interface: The board is programmed via the micro-USB connection, eliminating the need for external USB-to-Serial converters or additional hardware for programming.
Onboard LEDs: Like many Arduino boards, the Leonardo R3 includes built-in LEDs that can be used for debugging and indicating the status of the board or specific pins.

- 1 x Leonardo R3 Board Micro-USB compatible Without USB Cable
Works like it should no problems at all used for a led cube u made
Good quality and easy to use.
Awesome Arduino controller
I really like the colors. The USB cable is a good length and the board works flawlessly as a secondary joystick (programmed that way) on my PC.
Works well and relatively cheap. Good for diy sim controls.
Excellent quality and easy to use
Board is good. But there is a problem the usb port got detached soldering seems week. Good thing I know little soldering. Other than that it's great, using it for my DIY steering wheel.
What's not to love? Did EVERYTHING asked of it and never an issue. It's a Leonardo, plain and simple.Will be buying again, would absolutely recommend to others.
