For example, the Wi-Fi expansion board can be used when it is required to develop a
microcontroller-based application using a Nucleo development board to establish
Wi-Fi-based communication (e.g., an Internet application, or remote monitoring and control
application). All the user has to do is plug the Wi-Fi expansion board on top of the Nucleo
development board and power up the Nucleo board. The required software can then be de-
veloped easily using, for example, the Wi-Fi library provided by Mbed. In addition to the li-
braries, various sample programs are provided by Mbed for using the expansion boards in
projects. With the help of these libraries, a project can be developed in considerably less time
since the expansion board has already been tested and working. It is also an advantage that
the user does not need to know much about the configuration or the hardware design of the
expansion board.
