STM32 Wireless Microcontrollers (MCUs)

Dual-core, multi-protocol wireless STM32WB microcontrollers

With support for Bluetooth™ 5 and IEEE 802.15.4 wireless protocols, our STM32WB series of dual-core, ultra-low-power 2.4 GHz RF microcontrollers meets the requirements for a wide range of applications based on proprietary stacks and protocols.

Built on an Arm^® Cortex^®‐M4 and Cortex^®‐M0+ core architecture, these devices support multiple profiles and can run
Bluetooth™ 5/OpenThread protocols concurrently.

Harnessing the STM32Cube development ecosystem, designers benefit from a complete suite of tools that reduce application development time:

STM32CubeMonRF software tool for testing the RF performance of STM32-based devices
STM32CubeWB package that includes STM32Cube™ hardware abstraction layer (HAL), low-layer (LL) APIs, and middleware components as well as the STM32CubeMX graphical software configuration tool for use with STM32WB microcontrollers
STM32WB55 Nucleo Pack supporting Bluetooth™ 5 and IEEE 802.15.4 communication (P-NUCLEO-WB55)

STM32WB, the STM32 family’s pioneer in wireless connectivity, is easy to use, reliable and perfectly fitted for a wide range of industrial and consumer applications.

Getting started with STM32WB

Purchase a STM32WB55 Nucleo pack

Download the Free STM32CubeWB embedded software package containing the HAL, LL (low-layer) APIs, middleware, Bluetooth™ 5 certified stack and Open-Thread certified stacks. Then install ST’s STM32CubeMX graphical software configuration tool (Free) that supports pinout configuration, code generation and a power consumption calculator. Start with one of the many examples provided or build your own project.

To fine tune your application, or perform radio test or build your own profile down load and install STM32CubeMonitor-RF tool.
