ST25R3911B NFC 개발 보드
(ST25R3911B NFC Development Kit Embedded STM32 Controller
with Multi NFC Protocols)
개요
- 본 제품은 ST25R3911B NFC 리더 보드입니다.
- STM32F103R MCU 및 OLED 디스플레이, 사용자 버튼을 장착하고 있는 NFC 보드로 ISO18092, ISO14443A, ISO14443B , ISO15693, FeliCa와 같은 멀티 프로토콜을 지원합니다.
- 1.3인치 OLED를 이용하여 동작을 눈으로 확인할 수 있습니다.
- 보드상에 프로그래밍 인터페이스 및 UART 디버깅 인터페이스, 다른 장치를 연결할 수 있는 I/O 핀이 접근이 가능합니다.
특징
- Multi protocols support: ISO18092, ISO14443A, ISO14443B , ISO15693, FeliCa™
- Differential antenna design, output power up to 1.4W, longer sensing distance
- Embedded low-power capacitive sensor, allows sensing and capacitive wake-up, detecting the nearby card without enabling the magnetic field of the reader
- STM32F103RBT6 controller, easy for learning, evaluating, or direct integration, needs no other external controller
- 1.3" OLED display, allows visual operation
- Onboard SRAM, additional space to the inner RAM
- Micro SD slot, supports external TF card for storing data to be transferred via NFC
- 4x buttons, 2x user indicators, convenient for debugging
- Onboard programming interface, UART debugging interface, break out all the unused IO pins for connecting other user peripherals
- Customized acrylic case, protective and dust-proof, better looking
- Comes with development resources and manual
