Wireless connectivity

STM32WB MCUs can run Bluetooth LE 5.3 together with 802.15.4 wireless protocols, Zigbee or OpenThread protocols in concurrent modes. This enables more convenient device management during installation and configuration, and significantly improves overall user experience.

For seamless device interoperability, the STM32WB MCU supports Matter application layer.


System Peripherals

The entire STM32WB series enables entry-level features as well as more robust communication features for a wide variety of integrated wireless solutions.


Security & ID

In addition to its wireless and ultra-low-power features, STM32WB microcontrollers embed security features which reduce device maintenance needs and ensure end devices are trustable and cannot be cloned.


Development Ecosystem

Developers can get started quickly and develop applications easily using our STM32WB55 Nucleo pack which consists of 2 boards both with an STM32WB microcontroller enabling a wide range of wireless applications.
