1.Demo Board 설명서
1-1 개념 설명
BC-05 Demo Board는 블루투스 모듈 “ BC-05-B ” 의 동작을 확인하고
실험/실습 할 수 있도록 만들어진 실험용 보드이다.
1-2 동작 전압
본 보드는 DC 6.0V ~ DC 12V까지 동작된다.
다만 아답터 전원 사용시, DC 12Volts (HU10467-11002A) 사용을 권고 한다.
1-3 보드 구성 BLOCK DIAGRAM
*. 참고 : 스피커는 별도로 부착이 요구 됩니다. (임피턴스 : 32 옴 또는 헤드셋 이어폰)
참고사항 – 본 보드에 부착된 “ BC-05-B” 모듈은 MASK-VERSION으로 별도의 구
동 소프트웨어 없이 사용될 수 있다.
