본 제품은 0.96인치의 작은 OLED 디스플레이입니다.

128x64 해상도의 흰색 OLED 픽셀을 가지고 있으며, 각각의 픽셀은 컨트롤러에 의해 on/off 제어가 가능합니다.

OLED는 자체적으로 발광하기 때문에 백라이트가 필요하지 않아 전력을 절약 할 수 있으며, 높은 contrast를 가집니다.

모듈에 장착된 드라이버 칩은 SSD1306이며, OLED는 3.3V 전원 및 로직으로 동작하지만 모듈에 레벨쉬프터가 장착되어 있어 5V 장치에서도 사용이 가능합니다.

3.3V 전원에서 약 40mA가량을 소비합니다.

관련문서의 아두이노 라이브러리 및 예제 코드를 참고하십시오.

마이크로컨트롤러는 화면을 버퍼링하기 위해 1K 램 이상이 있어야 합니다.
