Hardware tools
This STM32WB Discovery Kit is the most cost-effective way
to quickly start developing with STM32WB5M module.
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 LE 5.2, OpenThread and Zigbee 3.0
connectivity stacks. All embedded software components
come with a full set of examples running on ST boards.
Software tools
STM32CubeMX
Enables faster development thanks to
its MCU pinout and clock congurator,
power consumption calculator and code
generation tools.
STM32CubeIDE
Is an Eclipse-based IDE which integrates
the features of the STM32CubeMX
conguration tool.
STM32CubeMonitor
Is a development tool dedicated to
wireless connectivity (STM32CubeMonRF)
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.
