Description
DEMO-CR95HF-A
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.
