STMicro has released two new Bluetooth 5.3/5.4 products with the STM32WB09 Cortex-M0+ wireless Bluetooth 5.3 LE microcontroller and the ST32WB1MMC Cortex-M0+/M4 Bluetooth 5.4 LE module for simpler designs, as well as the B-WB1M-WPAN1 evaluation board
The microcontroller integrates a balun and a 32 MHz crystal and is designed for 2-layer PCBs for reduced BOM costs and simplified circuitry. STMicro provides RF reference designs, IPD chip for easy impedance matching, Bluetooth Low Energy and Mesh stacks, software, tools, and resources for development.
The company says the STM32WB09 microcontroller is suitable for skilled designers and provides a tiny package that is one of the smallest on the market right now. The STM32WB09 is available now for “high-volume OEM applications” starting at $1.36 in the QFN32 package. Further information can be found on the product page.
STM32WB1MMC module key features:
STMicro explains the STM32WB1MMC wireless module is better suited to customers who do not have access to extensive engineering skills and resources so they can create Bluetooth LE products with little to no RF knowledge. This reduces project risks and enables customers to focus on firmware development. The module leverages the STM32Cube ecosystem with, for instance, power-consumption testing using the STM32CubeMX calculator and RF testing with the STM32CubeMonRF software tool.
STMicro also provides the B-WB1M-WPAN1 evaluation board with motion, temperature, and barometric-pressure sensors to quickly evaluate the STM32WB1MMC Bluetooth 5.4 LE module and get started with firmware development before the hardware design is ready.
Besides STMicro’s STM32CubeIDE, the development board is also supported in third-party IDEs such as IAR Embedded Workbench and MDK-ARM.
The STM32WB1MMC modules are in production now and available for $5.32 for orders of 10,000 units, while the B-WB1M-WPAN1 evaluation board goes for around $30 on STMicro eStore and distributors. More details may be found on the product page for the module.

An antenna built into the module! Firmware in the datasheet, not so much.
