STMicroelectronics STM32WB1MMC Bluetooth module and B-WB1M-WPAN1 evaluation board

STMicroelectronics’ STM32WB1MMC wireless module has been designed to make wireless connectivity simple. It contains a certified wireless microcontroller pre-integrated with external components needed for the radio system, as well as the Bluetooth software, and so bypasses many of the engineering challenges encountered when designing with chips.

The module helps product developers reduce project risks and build high-performing wireless products with only basic radio-frequency engineering skills. By doing so, users can focus on developing their own firmware to add value as the wireless functionality will be easy to use.

Built around the STM32WB15 MCU with 320 KB flash and 48 KB RAM, the all-in-one module is claimed to alleviate supply-chain headaches and lead-time issues and to help avoid certification delays. Bluetooth Low Energy 5.4 certified and with worldwide radio-equipment approvals, it provides a full reference design in an LGA package.

To make the module even easier to use, ST’s B-WB1M-WPAN1 evaluation board is ready to power up and start development. The board contains movement, temperature and barometric-pressure sensors that can be incorporated into the system, and other convenient features like an industry-standard connector for attaching an external antenna.

For application development, the evaluation board accelerates the design of Bluetooth connectivity for integration with other system components and can be used as a reference design to ease hardware engineering workload. Leveraging the STM32Cube ecosystem, the board eases both power-consumption testing using the STM32CubeMX calculator and RF testing with the STM32CubeMonRF software tool.
