Introduction
The STM32 Nucleo-32 board (NUCLEO-F031K6, NUCLEO-F042K6, NUCLEO-F303K8,
NUCLEO-L031K6) provides an affordable and flexible way for users to try out new concepts
and build prototypes with STM32 microcontrollers, choosing from the various combinations
of performance, power consumption and features. The Arduino Nano connectivity support
makes it easy to expand the functionality of the Nucleo-32 open development platform with
a wide choice of specialized shields. The STM32 Nucleo-32 board does not require any
separate probe as it integrates the ST-LINK/V2-1 debugger/programmer. The Nucleo-32
board comes with the STM32 comprehensive software HAL library together with various
packaged software examples, as well as direct access to mbed online resources at
http://mbed.org.
