드리머 나노 V4.0은 ATMEGA32U4가 내장되어 있어서 자동으로 시리얼을 잡아주는 특징이 있습니다. 따라서 아두이노 레오나르도와 같이 키보드 / 마우스 인터페이싱을 요구하는 프로젝트에 유용하게 사용될 수 있는 제품입니다.

INTRODUCTION

The Dreamer Nano V4.0 is a surface mount breadboard embedded version of the ATMEGA 32U4 with integrated Micro USB. It has everything that Arduino Leonardo has (electrically).Physically, it is just missing power jack to save space.

Using the ATmega32U4 as its sole microcontroller allows it to be cheaper and simpler. Also, because the 32U4 is handling the USB directly, code libraries are available which allow the board to emulate a computer keyboard, mouse, and more using the USB-HID protocol!

The Dreamer Nano v4.0 is compatible with most Nano shield in the market. It's suitable for projects that require a compact size controller system. 

Note: The pins supporting I2C/TWI is located at digital pins D2(SDA) and D3(SCL).
