회사에서는 멀티 충전기로 했어서 그런가 wifi 꽂고나서는 안켜지던데
집에서 5V 2A 짜리 단독으로 물리니 문제없이 작동한다.
인터넷 찾아봐도 소비전력 이야기가 딱히 없던데(몇 mW 라던가..) 그냥 그러려니 하고 써야하나?

mini-pciex도 아니고 왜 m.2로 만드는진 모르겠지만
아무튼 m.2 폼팩터의 무선랜이고
i-pex의 MHF4 (혹은 ipex4라고 표기) 커넥터의 듀얼 안테나 제품이다.
랜카드가 7천원 + 3천인데

MHF4가 2800원 + 3천원. 배보다 배꼽이 더 큰 느낌이고
그 와중에 저건 또 케이블이라 SMA 2.4GHz 안테나가 필요하다는 것 이 또 추가지출을 하게 하네..
(회사에서 뽀려야지 -_-)
