STM32 Nucleo-64 boards (MB1136)
Introduction
The STM32 Nucleo-64 boards based on the MB1136 reference board (NUCLEO-F030R8,
NUCLEO-F070RB, NUCLEO-F072RB, NUCLEO-F091RC, NUCLEO-F103RB,
NUCLEO-F302R8, NUCLEO-F303RE, NUC
LEO-F334R8, NUCLEO-F401RE,
NUCLEO-F410RB, NUCLEO-F411RE, NU
CLEO-F446RE, NUCLEO-L010RB,
NUCLEO-L053R8, NUCLEO-L073RZ, NUCLEO-L152RE
, NUCLEO-L452RE,
NUCLEO-L476RG
) provide an affordable and flexible way for users to try out new concepts
and build prototypes with the STM32 microcontrollers in the LQFP64 package, choosing
from the various combinations of performance, power consumption, and features. The
ARDUINO
®
Uno V3 connectivity support 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 STM32 Nucleo boards do not require any separate probe
as they integrate the ST-LINK/V2-1 debugger and programmer. The STM32 Nucleo boards
come with the comprehensive free software libraries and examples available with the
STM32Cube MCU Packages, as well as direct access to the Arm
