The STM32 Nucleo-64 board provides users with an affordable and flexible way to try out concepts and build prototypes by choosing from a wide range of performance and power feature combinations available with STM32 microcontrollers. For compatible single boards, an internal or external SMPS significantly reduces power consumption in Run mode. for Arduino Uno V3 connectivity support and ST morpho headers allow the functionality of the STM32 Nucleo open development platform to be easily extended with a wide selection of professional shields. The STM32 Nucleo-64 board does not require any separate probes as it integrates the ST-LINK debugger/programmer. The STM32 Nucleo-64 board comes with STM32's comprehensive free software libraries and examples for use with the STM32Cube MCU package.
