라즈베리 파이 2 시리얼 연결!

핀 배열은 B+ 것을 참고!

2015/02/26 - [개소리 왈왈/라즈베리 파이 2] - 라즈베리 2 하드웨어 관련 정보 및 win10 IoT


외곽의 위에것 부터

+5 +5 GND TX RX 이니 3개를 띄우고 4번째 5번째를 연결한다. 



그리고 TX와 RX를 서로 꼬아 연결해주면

(USB TO TTL의 TX는(보라) RX는(회색) <-> 라즈베리의 4번 핀 TX(회색) 5번핀 RX(보라)


시리얼로 접속하면 펄풱!

115200 bps 로 접속하면 된다.


드라이버는 옥션 페이지 상에 연결된 scipia 에 업로드 되어 있는데

PL2303으로 나중에 찾을일이 생길 지...도?

[링크 : http://www.scipia.com/downloads/PL2303_Prolific_DriverInstaller_v1.5.0.rar]

[링크 : http://itempage3.auction.co.kr/DetailView.aspx?ItemNo=A615604872]


아무튼 가격은 2800원으로

내가 개고생 해가면서 MAX232 로 땜질하며 쑈하는거 보다 싸고 간편하고 깔끔하다! ㅋ



특이(?)하게도 부트로더 없이 바로 뜨는 듯한 콘솔 메시지의 시작이 보인다.
