Dreamer Nano Arduino Leonardo Compatible Board

The Dreamer Nano V4.1 from DFRobot is a breadboard-compatible, compact version of the ATmega 32u4. Apart from the power jack, this board is electrically identical to the Arduino Leonardo, only physically much more compact. Since the Atmega 32u4 has a USB interface, code libraries are available that enable the board to emulate a computer keyboard, mouse and more via the USB-HID protocol. The Dreamer Nano V4.1 is compatible with most Nano Shields on the market. It is suitable for projects that require a compact control system.
