전원부가 튼실한 USB허브 만들려고 몇개 구입했다가 그냥 사용 하고있습니다
제가 뜯어본 저렴한 USB 허브의 컨트롤러는 대부분 FE1.1S 칩이였습니다(딱히 불편 한건 없지만)
이건 상용 장비에서 많이 보이는 GL852가 사용되었군요
전원쪽도 튼실하고, 딱히 더 추가하거나 뺄게 없었습니다
정확한 용도는 알수 없으나 잘 만들어진 국산 USB 허브임에는 틀림없습니다
혼자 사용하기 아까워 공유합니다

GL852 HUB Controller 사양
http://www.sunnyqi.com/upLoad/product/month_1308/GL852G.pdf
4Port 이상 필요한 경우(USB2507 Microchip 7Port Hub Conrroller)
http://www.illuwatar.se/project_pages/usb-hubb/files/USB-hubb.pdf
USB2507 는 9,000원 정도에 부품 사이트 에서 구매가능
* 이런거 1,000원이면 공짜입니다 나중에 사용하실일 반드시 생깁니다 구입해두셔도 손해 안보실거 같네요
* 저는 그냥 장비 옆에다 대충 걸쳐 두었는대, 손재주 좋으신분들 적당한 케이스에 넣으신거 공유해주면 좋겠네요
** 개요 4Port 외부 전원 USB HUB **
PC/Notebokk 쪽 커넥터는 USB B Type 커넥터
USB 1,2,3은 일반 USB A Type 커넥터
USB 4 사용시 적절한 커넥터 연결 혹은 납땜하여 사용
* Type별 USB Connnector
http://pc-level.com/wp-content/uploads/2010/01/usb-connectors.JPG
* 커넥터 핀 배열 사진 클릭하시면 크게 보입니다(첫번째 사진)
* 전원을 연결 하셔야 동작 합니다
* 외부전원없이 사용하는건 의미가 없습니다 (무부하시 자체 소비전류 13mA)
* 특히 RS-232C <-> USB 컨버터 사용하시는 분들은 외부전원 USB 허브가 필수입니다
* USB 1,2,3은 서지 프로텍터가 있으며 장비 파손의 피해를 최소화 해줍니다(PCB 뒷면, 0805 사이즈 초록색 칩저항 처럼 생긴것.. 생긴거와 달리 비싼 부품입니다)
* USB 포트 최대 전류는 500mA입니다, 4Port이므로 6V ~24V 2.5A이상 되는 전원장치를 사용하세요(6V~12V권장)
- 전원 어댑터 2개 사실거 하나 사신다는 생각으로 가능하면 국산 구입하세요

- 트랜스포머가 들어간 전원장치를 사용해야 할때가 있어 추천해드렸지만 사양을 다시 보니 230V 50Hz입니다 웅~ 하는 험이 생길거 같습니다 비추입니다
