STM32WBxM Modules

CAD Resources


The STM32WB5MMG wireless module addresses 2.4 GHz solutions with Bluetooth® LE, and 802.15.4 protocols, including Zigbee, Thread, as well as proprietary protocols.

Based on the STM32WB55 MCU which offers 1 Mbyte of Flash and is packaged in WLCSP100, this module is ready-to-use and embeds the full reference design up to the antenna for faster market introduction. 

It offers performance, multi-protocol flexibility, security features, the same ultra-low power features as STM32WB MCUs, and its certifications ensure wide geographical coverage.  
Fully part of the STM32WB portfolio, the STM32WB5MMG is included in ST’s longevity program, ensuring continuous supply for 10 years.

Wireless connectivity



The STM32WB5MMG module supports the same wireless protocols as the STM32WB series: it is certified for running Bluetooth® LE 5.0 with multiple profiles, Zigbee PRO with Zigbee 3.0 clusters, and OpenThread for MTD and RFD modes.

Proprietary protocols can be accessed in multiple ways using BLE LLD, HCI or generic MAC device configuration, depending on application requirements.

The STM32WB5MMG module includes 1 Mbyte of Flash memory, ensuring your application runs smoothly with all protocol stacks, in standalone and in concurrent mode.

Package information and development ecosystem

STM32WB5Mx wireless microcontroller module is based on an LGA86 package (7 x 11.3 mm). Its small form factor provides designers minimal footprint and sufficient memory size for straightforward integration in any end-product, without needing any background knowledge on radio.

The pinout implementation enables a 2-layer PCB with main communication channels and peripherals, and 4 layers for the complete solution.

The STM32WB5xM module is fully integrated into the STM32Cube ecosystem and is certified for major geographical EMC compliance areas.

To ensure wide geographical coverage, the STM32WBxM complies with the following standards: CE for Europe, FCC for USA, JRF for Japan, SRRC for China, GOST for Russia, KC for Korea, NCC for Taiwan.

The STM32WB55 Nucleo pack and STM32Cube Ecosystem form a consistent set of software development tools to quickly and easily start developing your application.

Fully integrated in the market-proven STM32Cube ecosystem, the STM32WB55 Nucleo pack comes with a comprehensive set of embedded software resources and development tools.

The STM32CubeWB MCU Package is a one-stop-shop solution for embedded software resources and features HAL and LL peripheral drivers, a full set of middleware and radio stacks (Bluetooth LE 5.0, OpenThread, Zigbee 3.0, open protocols and concurrent modes)  together with various preconfigured software examples for several popular IDEs such as Keil MDK-ARM and IAR Systems.

The STM32WBxM module is compatible with the STM32CubeMX MCU initialization, configuration and code generation tool, and with STM32CubeMonRF software to test and validate RF performance.
