Arduino® Leonardo with Headers

The Arduino® Leonardo with Headers is a versatile microcontroller board based on the ATmega32u4. Unlike earlier Arduino boards, the Leonardo integrates USB communication directly into the microcontroller, allowing it to appear to a connected computer as a mouse, keyboard, or a virtual serial port. This makes the Leonardo a great choice for projects that require direct interaction with a computer, such as custom input devices.
