STM32 Nucleo-64-P boards (MB1319)
Introduction
The STM32 Nucleo-64-P boards, based on the MB1319 reference board (NUCLEO-
L412RB-P, NUCLEO-L433RC-P, and NUCLEO-L452RE-P), provide an affordable and
flexible way for users to try out new concepts and build prototypes with the STM32
microcontroller and the external SMPS (switched-mode power supply), which provides
various combinations of performance, power consumption, and features.
ARDUINO® Uno V3 connectivity and 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-64-P boards do not require any separate probe, as they integrate the
ST-LINK/V2-1 debugger/programmer. The STM32 Nucleo-64-P boards come with the
comprehensive free STM32 software libraries and examples that are available with the
STM32Cube package.
