흐음.. 역시 장비가 좋아야 해...
(대충 인두기를 사고 싶다라는 이야기)
ESP32-CAM에는 AMS1117 이라는 놈이 달려있는데
연구소에 있는 부품중에 1117로 검색해보니 IL1117C-3.3 뿐이라고 해서
핀 호환되는지 보니 일단 okay
[링크 : https://www.alldatasheet.co.kr/datasheet-pdf/pdf_kor/259210/IKSEMICON/IL1117-3.3.html]
에잇 날려먹으면 새로 사지! 라는 마음에 했는데 오오 작동된다!! 만세!!
(근데 먼가 지르려고 잔뜩 장바구니 넣었는데 살 이유가 사라졌...)

SG90 서보라고 해서 구매했는데 무한으로 돌고 있어서
서보형 모터인줄 알았는데 이런 비밀이!!
일단은 내일 출근하면 서보 구경시켜 달래서
옆에 가변저항이 있는지 봐야겠다 -ㅁ-

이거.. 모양만 서보지 실은 기어드 모터 아님?!?!
SG90 모터의 무한회전 버전입니다. 일반 각도 지정 서보모터와 다르게 입력 값에 따라 정/역회전 및 속도가 변화합니다. 90도에서 멀어질수록 회전 속도가 빨라지는 특성을 가집니다. |

esp32-cam 부팅이 안되서 확인해보니
계속 brown out detected -_-
레귤레이터 찍어보니 3.3V가 나와야 하는데 2.6V가 나오네
5V to 3.3V 레귤레이터를 좀 사둬야 하나...
그나저나 5V에서 3.3V면 1.7V 강하인데 2.6V 면은 2.4V 강하인데
머가 이상이 생겨서 더 떨어진걸까?
처음살때 찍은건데, LDO 에 흠집이 없어 보이는데
AMS1117의 S아래에 점 같은 손상흔적
열때문에 터진건가..
