More info


The Nucleo development kit with the STM32 microcontroller allows you to easily try new solutions and build prototypes. The board is equipped with a connector compatible with Arduino Nano. The built-in ST-LINK programmer / debugger is a great help, it can operate in three modes: mass storage, virtual COM port or debugger port. The programmer cooperates in many popular programming environments such as IAR, Keil, STM32CubeIDE and others based on GCC.
