Wireless module offers easy way to implement Bluetooth connectivity

The STMicroelectronics STM32WBA5MMG is a complete 2.4 GHz wireless module which supports the implementation of Bluetooth® Low Energy v5.4, Zigbee^® 3.0 and OpenThread connectivity in an embedded system design.

Based on the STM32WBA55UG wireless microcontroller, the module is supplied with royalty-free RF protocol software, and is suitable for use by any developer, no matter the level of their RF expertise and knowledge. The module incorporates the external components required to implement a short-range wireless transceiver, including 32 MHz and 32 kHz crystals and an integrated antenna. An external antenna option is also available. 

The use of a module provides for accelerated time to market as the device can be implemented in a simple, low-cost 2-layer PCB design. It is supplied with a comprehensive set of certifications, including CE, FCC, ISED, MIC, RoHS and REACH. 

The module is suitable for low-power applications requiring Bluetooth Low Energy connectivity. It also supports IEEE 802.15.4 radio signaling for Thread and Zigbee networking, including in concurrent communication mode. 

The STM32WBA5MMG provides best-in-class RF performance thanks to its good receiver sensitivity and high output signal power. Advanced security features protect both the module and its data. 

Developers working with the STM32WBA5MMG can benefit from the STM32CubeWBA, a free software package which includes a hardware abstraction layer, low-level application programming interfaces, Arm^® CMSIS support, a file system, real-time operating system, RF protocol stacks, and code examples. 

The STM32WBA5MMG is supplied in a SiP-LGA76 package with a 12.5 mm x 8.0 mm footprint.
