위 링크에 있는 내용대로, 버팔로 WZR-HP-G300NH 유무선 공유기의 시리얼 포트 디버깅에 성공하였습니다.

위 링크의 UART-USB 보드를 구매하였지만, 입력 전압이 틀린 관계로 별수 없이 DC-DC 레귤레이터를 제작하여 연결하였습니다.
5V DC to 3.3V DC 레귤레이터는 LM317T 룰 이용하여 제작하였습니다.
제작방법은 다음 링크를 참조하였습니다.
http://miy-makeityourself.blogspot.com/2010/08/33v-regulated-voltage-supply.html
사진에 보이는 바와 같이, Molex 커넥터를 이용하여, 3단 연결을 해서, 약간 선이 길게 나오기는 했지만, 디버깅은 잘 되는 것 같습니다.
다음은 D-Link DIR-825를 시리얼 디버깅 시도할 차례입니다.
개봉박두~~.
다음은 시리얼 디버깅되는 내용을 캡쳐한 것입니다.
