NUCLEO-L433RC-P

STM32 Nucleo-64 development board with STM32L433RC MCU, SMPS, supports Arduino, ST Zio and morpho connectivity

Overview

The STM32 Nucleo board provides 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.

The Arduino™ Uno V3 connectivity support and the ST Morpho headers allow to expand easily the functionality of the STM32 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 and programmer.
