13.56Mhz RFID 읽기/쓰기 모듈
(13.56MHZ RFID Reader/Writer Module V4)
개요
- 본 제품은 MFRC522 기반의 RFID 읽기/쓰기 모듈입니다.
- ISO14443A/Mifare 및 mifare classic을 지원하며 양방향으로 848kbit/s의 통신 속도를 지원합니다.
- 모듈에는 마이크로컨트롤러가 장착되어 있어 MCU의 펌웨어가 제공하는 API를 통해 읽기/쓰기 동작을 수행할 수 있습니다.
- 모든 명령은 UART를 통해 통신합니다.
- 모듈의 SPI 인터페이스는 MFRC 칩의 SPI 인터페이스로 이 인터페이스로 칩을 직접 접근 할 수 있습니다.
- 아래는 지원가능한 태그입니다.
