NUCLEO-L433RC-P ARM STM32 Nucleo-64 development board ( SMPS, MCU, supports Arduino)

The STM32 Nucleo-64-P boards (NUCLEO-L433RC-P, NUCLEO-L452RE-P) provide an affordable and flexible way for users to try out new concepts and build prototypes with the STM32 microcontroller, choosing from the various combinations of performance, power consumption and features.

Arduino™ Uno V3 connectivity, and ST morpho headers provide an easy means of expanding the functionality of the Nucleo open development platform with a wide choice of specialized shields. The STM32 Nucleo-64-P board does not require any separate probe as it integrates the ST-LINK/V2-1 debugger/programmer. The STM32 Nucleo-64-P board comes with the STM32 comprehensive software HAL library, together with various packaged software examples.
