2 Hardware description
This section describes the X-NUCLEO-NFC3A1 features and provides information which
could be useful to understand the board schematic diagrams.
2.1 X-NUCLEO-NFC03A1 board
The board allows the user to test the functionality of the CR95HF integrated circuit. The
CR95HF supports reader/writer mode and supports following communication protocols:
ISO/IEC 14443 Type A and B, ISO/IEC 15693, ISO IEC18092, MIFARE ® Classic.
Its functionality can be exploited using the firmware package contained in the X-CUBE-
NFC3. It is fundamental to program the microcontroller on the STM32 Nucleo board. Please
refer to user manuals UM1724 and UM1725, available on www.st.com.
The CR95HF integrated circuit module and the STM32 Nucleo board are connected
through connectors CN5, CN6, CN8 and CN9 (see Table 1: "Interconnection between
STM32 Nucleo board and X-NUCLEO-NFC03A1 left-side connectors" for details).
