 Hello, and welcome to this video explaining how to get started with the Dynamic NFC Tag STM32 Nucleo Expansion Board. This board is part of the STM32 Open Development Environment, a fast and affordable way to prototype and develop innovative devices and applications with state-of-the-art ST components. Information on how to obtain the board can be found on st.com.xnucleo under the reference xnucleo nfc01a1. The package includes the board itself and an insert card that provides a first level of information on the main features. The board is built around the M24SR Dynamic NFC Tag IC and a double layer inductive antenna etched on the PCB. It is equipped with an Arduino Uno R3 connector, allowing it to be plugged into an STM32 Nucleo Development Board. To start building your prototype, plug the STM32 Nucleo Expansion Board onto an STM32 Nucleo Development Board. The list of compatible boards can be found on st.com. Next, connect the STM32 Nucleo Development Board to a PC using a mini USB cable. The board is automatically detected and seen as a disk drive. Visit st.com and search for the keyword xnucleo nfc01a1. Click on the main part number link. Then go to the tools and software section and click on the xcube link. Finally, go to the end of the page and click on the download button in the get software section. When downloaded, just unzip the file in the folder you want. In the software package, you will find directories with all the required material. Now, let's try a sample application which opens a web link on an nfc-enabled smartphone when it is brought near the nfc tag. The firmware to be installed is called writeuri and can be found in the example folder of the projects directory, as shown here. Select the STM32 Nucleo Development Board you are using and drag and drop the binary file onto the Nucleo disk drive. Bring your smartphone near the nfc tag on the expansion board. The web browser automatically opens and displays the st.com web page. Discover more features and software add-ons on st.com slash open software. Blue MicroSystem is a full-featured software development framework, providing all the required libraries to develop applications using the motion and environmental sensors, Bluetooth low energy, and dynamic nfc tag expansion boards.
