STM32 Nucleo-64 boards (MB1360)
Introduction
The STM32 Nucleo-64 boards, based on the MB1360 reference board (NUCLEO-G070RB,
NUCLEO-G071RB, and NUCLEO-G0B1RE order codes) 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 se
parate probe, as they integrate the
ST-LINK/V2-1 debugger/programmer. The STM32 Nucleo-64 boards come with the
com
prehensive free STM32 software libraries and examples that are available with the
STM32CubeG0 MCU Package.
