STM32 Nucleo开发板

The STM32 Nucleo board (NUCLEO-F103RB, NUCLEO-L152RE, NUCLEO-F401RE, NUCLEO-F030R8, NUCLEO-F072RB) 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 ArduinoΤΜ 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.
