STM32 Nucleo-64 board (MB2046)
Introduction
The STM32 Nucleo-64 board, based on the MB2046 reference board
(NUCLEO-C071RB
order code) provides an affordable
and flexible way for users to test new concepts and build prototypes 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 STM32 Nucleo open development platform with a wide choice of specialized shields.
The STM32 Nucleo-64 board requires no separate probe, as it integrates the STLINK-V2EC debugger/programmer.
The STM32 Nucleo-64 board comes with comprehensive free STM32 software libraries and examples available with the
STM32CubeC0
MCU Package.
