1 Getting started

Connect the X-NUCLEO-NFC05A1 to an STM32 Nucleo-64 development board. The PC
USB port has to be capable of delivering at least 300 mA at 5 V supply. A demo software is
available for download at www.st.com to be programmed onto the STM32 Nucleo.

1.1 Hardware requirements

The X-NUCLEO-NFC05A1 expansion board is designed to be used with any STM32
Nucleo board, although complete testing has been performed using the NUCLEO-L476RG
hosting the STM32L476RG microcontroller.

The STM32 Nucleo firmware and the related documentation are available at

http://www.st.com/stm32nucleo.

1.2 System requirements

To use the STM32 Nucleo boards with the X-NUCLEO-NFC05A1 expansion board the
following software and hardware are required:

 an STM32 Nucleo-64 development board
 a Windows® PC to install the firmware package
 a USB type A to Mini-B USB cable to connect the Nucleo board to the PC
 unit must be supplied by a safety extra low voltage (SELV) limited power source

through the USB port, the source should not exceed 60Vdc / 8A / 100VA

To install the board firmware package (order code: X-CUBE-NFC5) the PC must have:

 128 MB of RAM
 40 MB of free hard disk space

The X-CUBE-NFC5 firmware and the related documentation are available at www.st.com.
