ST STM32G4 Nucleo-32 User Manual

Introduction
The STM32G4 Nucleo-32 board (NUCLEO-G431KB) provides an affordable and flexible way for users to try out new concepts
and build prototypes, by choosing from the various combinations of performance, power consumption and features provided by
the STM32G4 Series microcontroller. The ARDUINO
®
Nano V3 connectivity provides easy means of expanding the functionality
of the Nucleo open development platform with a wide choice of specialized shields. The STM32G4 Nucleo-32 board does not
require any separate probe as it integrates the STLINK-V3E debugger/programmer. The STM32G4 Nucleo-32 board comes
with the comprehensive free software libraries and examples available with the STM32CubeG4 MCU Package.
