HARDWARE TOOLS
This STM32 Nucleo pack is the most cost-effective way to
quickly get started developing STM32WB-based prototypes.
Order code: P-NUCLEO-WB55
EMBEDDED SOFTWARE
The STM32CubeWB package includes the STM32Cube
hardware abstraction layer (HAL) and low-layer (LL)
APIs peripheral drivers, a consistent set of middleware
components (RTOS, USB, FatFS and STM32 touch
sensing), as well as Bluetooth 5.0, OpenThread and
ZigBee 3.0 connectivity stacks. All embedded software
components come with a full set of examples running on
STMicroelectronics boards.
SOFTWARE TOOLS
STM32CubeMX
Enables faster development thanks to
its MCU pinout and clock congurator,
power consumption calculator and code
generation tools.
STM32CubeIDE
Is an Eclipse-based IDE which integrates
the features of the STM32CubeMX
conguration tool.
STM32CubeMonRF
Is a development tool dedicated to
wireless connectivity which helps reduce
time-to-market by enabling radio testing
and beaconing.
STM32CubeProg
Is an all-in-one software tool for
programming STM32 devices which can
be easily used to interact with the memory
of the STM32WB, including secure
programming of the RF stacks.
STM32WBx0 VALUE LINE
Extending our portfolio, the STM32WB50 Value Line focuses
on the essentials and offers a feature-optimized solution
to help developers meet the design requirements of cost-
sensitive industrial and consumer IoT applications.
The STM32WB55 Nucleo pack is a useful tool to quickly get
you started with the STM32WB50 microcontrollers.
Companion chip
