STM32 Nucleo-64 boards (MB1932)
Introduction
The STM32 Nucleo-64 boards, based on the MB1932 reference board (order codes
NUCLEO-U083RC
and NUCLEO-U031R8),
provide an affordable and flexible way for users to test new concepts and build prototypes with the STM32 microcontroller with
different combinations of performance, power consumption, and functionality.
®
The ARDUINO
Uno V3 connectivity support and the ST morpho headers provide an easy means of expanding the functionality
of the STM32U0 Nucleo open development platform with a wide choice of specialized shields.
The STM32 Nucleo-64 board does not require any separate probe, as it integrates the STLINK-V2EC debugger/programmer.
The STM32 Nucleo-64 board comes with the comprehensive free STM32 software libraries and examples that are available
with the
STM32CubeU0
MCU Package.
