ST STM32G4 Nucleo-64 User Manual

Introduction
The STM32G4 Nucleo-64 boards based on the MB1367 reference board (NUCLEO-G431RB, NUCLEO-G474RE) provide an
affordable and flexible way for users to try out new concepts and build prototypes with the STM32G4 Series microcontrollers,
choosing from the various combinations of performance, power consumption and features. The Arduino
™
Uno V3 connectivity
and the 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 STM32G4 Nucleo-64 boards do not require any separate probe as they integrate
the STLINK-V3E debugger/programmer. The STM32G4 Nucleo-64 boards come with the comprehensive free software libraries
and examples available with the STM32CubeG4 MCU Package.
