The STM32 Nucleo board （NUCLEO-F030R8， NUCLEO-F072RB， NUCLEO-F103RB，

　　NUCLEO-F302R8， NUCLEO-F334R8， NUCLEO-F401RE， NUCLEO-F411RE， NUCLEOL053R8， NUCLEO-L152RE） provides an affordable and flexible way for users to try out new

　　ideas and build prototypes with any STM32 microcontroller lines， choosing from the various

　　combinations of performance， power consumption and features. The Arduino?

　　connectivity support and ST Morpho headers make it easy to expand the functionality of the

　　Nucleo open development platform with a wide choice of specialized shields. The STM32

　　Nucleo board does not require any separate probe as it integrates the ST-LINK/V2-1

　　debugger/programmer. The STM32 Nucleo 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 mbed.org.
