STM32 Nucleo-64 boards with STM32G07xRB MCUs
Introduction
The STM32 Nucleo-64 boards (NUCLEO-G070RB and NUCLEO-G071RB) provide an
affordable and flexible way for users to try out new concepts and build prototypes with the
STM32 microcontroller, which provide various combinations of performance, power
consumption and features.
Arduino™ Uno V3 connectivity and ST morpho headers provide easy means of expanding
the functionality of the Nucleo open development platform with a wide choice of specialized
shields.
The STM32 Nucleo-64 boards do not require any separate probe, as it integrates the
ST-LINK/V2-1 debugger/programmer. The STM32 Nucleo-64 boards come with the
comprehensive free STM32 software libraries and examples that are available with the
STM32Cube package.
