구매한게 전부 동작이 안되므로 주의(?)를 당부하는 사용기를 봤습니다(Firmware Write가 안된다는 말이겠죠?)
뭐가 안된다면 정말 안돼? 괜한 호기심이 발동합니다

결론 부터 말씀드리면 잘 되며, 표준 6Pin ISP 커넥터를 사용합니다(첫번째사진)

판매글로는 크기가 감이 오지 않습니다,  손바닥만한 크기를 예상했었는대
받고 보니 가로x세로 크기가 15cm x 11Cm 의 대형 PCB더군요(두번째 사진)
ADC 포트 3개의 입력중 한개는 전압이 1V 이하로 떨어지면 알람이 발생하고
MAX232를 통해 RS-232C 통신을 한다는거 이외 포트에 나오는 신호도 확인해봤지만
흥미를 느낄 만한게 없어 더 이상 파악 하지 않았습니다

Firmware 크기가 14K 정도,  ADC 3개입력, RS-232C 통신,  PWM 신호
그 정도 처리하기에는  ATmega128A가 Overspec인거 같은 느낌이 들더군요
깊은 사정은 모르겠으나 아마 7 Segment 구동을 위해 포트가 많이 필요했을거란 추측만 합니다

PCB 크기도 크고, 용도파악도 안되고 그대로 사용하기엔 무리가 있다고 판단,  부품 활용이 적절해 보입니다
주요부품 목록은 아래와 같습니다

ATmega128,
7 Segment(4EA), 
MAX232, 
446mH 인덕터(3EA),
OP Amp LF353(5EA), OP07C(3EA), 
LS47 BCD-to-Seven-Segment decoders/Drivers (1EA)
NNRA MAX66DM, 500옴 가변저항(3EA), 부저(Tranduser)외 

인덕터 부품 표면에 용량 표기가 없습니다, LCR 미터로 확인 해보니 446mH 정도 되었습니다
내부에 용량표기가 있을까라는 생각에 수축 튜브를 제거 해보았지만 부품만 망가트렸습니다(3번째 사진)

* LCD,VFD, 기타 PCB 제품들은 전용 포장 용기에 담겨있지 않고 벌크로 쌓여있을 경우 분해, 적출시
  익덕터,Capacitor 같은 돌출된 부품들은 물리적 손상이 가해져 떨어져 나가는 경우가 허다합니다
* 사진에 보이는것도  작업하기전 PCB를 조사해보니 PNP TR 하나가 깨져있더군요
* 물리적 손상은 육안으로 식별이라도 되지만 전기적 손상은 시간도 많이 걸리고 불확실성이 많아 최소 2개이상 준비되어야 그나마 분석시 고장여부, 활용여부 판단이 쉽습니다
