STM32G474RE MCU-based STM32 Nucleo-64 development board supports Arduino and ST morpho connectors. STM32 Nucleo-64 boards provide a cost-effective and flexible way for users to experiment with various performance and power consumption features provided by the STM32 microcontroller, allowing them to try out new concepts and create prototypes by selecting different combinations. For compatible boards, an external SMPS significantly reduces power consumption in run mode. The STM32 Nucleo-64 board doesn't require a separate probe because it integrates the ST-LINK debugger/programmer.
