아두이노 퓨즈비트 설정관련

기본값으로 설치되었다는 전제하에

아래 경로에 플래시 구울때 사용하는 설정들이 존재한다.

아두이노는 기본적으로 USB 파워나 외부 전원을 통해(7805) 5V를 공급하도록 되어있는데

7805를 들어내거나 결선을 바꾸거나 외부 Vcc에다가 3.3V를 넣어 주고

클럭을 다운시켜 작동하면 좀 간편할지도?

아니면 프로미니 3.3V 이런거라던가?

ATmega328 running at 8MHz with external resonator (0.5% tolerance)

Low-voltage board needs no interfacing circuitry to popular 3.3V devices and modules (GPS, accelerometers, sensors, etc)
