We are announcing the commercial availability of the first STM32WB microcontrollers, theSTM32WB55 family of MCUs in four different packages: QFN48, QFN68, WLCSP100, and BGA129. We introduced the STM32WB a year ago when it was sampling, and it remains the first and only dual-core Cortex-M4 and Cortex-M0+ MCU on the market certified Bluetooth Low Energy v5.0, and 802.15.4. To accompany the arrival of these components, we are also launching STM32CubeMonRF, a software tool to help developers test and setup their radio more efficiently. We are also launching the P-NUCLEO-WB55 a development pack containing a classical Nucleo 64 board and a USB dongle. They both ship with demo application on the MCU to offer a truly unique experience right out-of-the-box..
