리눅스 포럼리눅스 Wifi 모듈 Carambola2
2015.05.05 21:49
안녕하세요, 여러 연구(?)를 마치고 오랜만에 복귀했습니다.^^
2015년 2월쯤에 구매하여 3월에 도착한 8Devices Carambola2 입니다.
400MHz Atheros AR9331 CPU와 16MB FLASH, 64MB RAM을 가지고 있는 무선 모듈입니다.
(임베디드 시스템중에는 꽤 높은 사양이죠.)
리눅스 OpenWrt (커널 3.7)를 운영체제로 사용하고 있습니다.
랜포트 2개와 USB, 시리얼 콘솔도 지원됩니다.
Carambola2 케이스입니다. 손바닥보다 조금 작은 크기입니다.
Carambola2의 핀 구조입니다.
USB를 연결한 사진입니다.
시리얼로 연결해서 부팅 로그를 가져와봤습니다.
