STM32G0 Nucleo-32 board (MB1455)
Introduction
The STM32G0 Nucleo-32 board based on the MB1455 reference board (NUCLEO-G031K8) provides an affordable and flexible
way for users to try out new concepts and build prototypes by choosing from the various combinations of performance and
power consumption features, provided by the STM32G0 microcontroller.
™
The Arduino
Nano V3 connectivity support allows the easy expansion of the functionality of the STM32 Nucleo open
development platform with a wide choice of specialized shields.
The STM32G0 Nucleo-32 board does not require any separate probe as it integrates the ST-LINK/V2-1 debugger/programmer.
The STM32G0 Nucleo-32 board comes with the STM32 comprehensive free software libraries and examples available with the
STM32CubeG0
MCU Package.
