Description
The DEMO-CR95HF-A is a demonstration kit which allows to evaluate the performances of ST CR95HF 13.56 MHz multiprotocol contactless transceiver. It includes a ready-to-use board to interface with the CR95HF host PC demonstration software through an USB interface. 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. Figure 1. Functional block diagram
