CR95HF演示板用于评估ST CR95HF 13.56 MHz多接触式收发器的性能,它包括一个使用USB接口与CR95HF 主机演示软件连接的电路板。The DEMO-CR95HF-A is powered through the USB bus and no external power supply is required. It includes a CR95HF contactless transceiver, a 47 x 34 mm 13.56 MHz inductive etched antenna and its associated tuning components.By default, the CR95HF communicates with the STM32F103CB 32-bit MCU via the SPI bus. The interface can then be changed to UART.At the end of the initialization, the DEMO-CR95HF-A launches a tag tracking operation. When an RFID or NFC tag is identified, the LED is turned on.
