NUCLEO-WB55RG, a Simpler Development Board for the STM32WB MCU

    ST is announcing today the release of the NUCLEO-WB55RG development board, which offers a more straightforward layout and enables developers to work with devices that rely on Bluetooth LE, Zigbee, Thread, or 2.4 GHz proprietary protocols. Indeed, the new model now hosts the MLPF-WB55-01E3, a 2.4 GHz matched filter companion chip for the STM32WB55. The MLPF-WB55-01E3 integrates passive devices to reduce the bill of materials and increase the overall RF performance. Additionally, the ability to support multiple wireless protocols further simplifies developments. Programmers can work on Bluetooth LE, Zigbee, Thread, 802.15.4, and concurrent modes application on the same board.

    From the P-NUCLEO-WB55 to the NUCLEO-WB55RG, Lowering the Barrier to Entry

    When ST first launched the STM32WB, we also released the P-NUCLEO-WB55. The MCU remains the only dual-core wireless microcontroller in the industry with a 2.4 GHz radio and certified Bluetooth LE, Zigbee, and OpenThread radio stacks. By including all these components under the same MCU package, engineers get the benefits of an integrated system. For instance, the device lowers the barrier to entry to wireless applications by offering a simpler approach. The P-NUCLEO-WB55 reflected this desire for greater accessibility by including a Nucleo board and a USB dongle. Indeed, the pack enabled developers to send packets between two devices rapidly for instant demos. Since the latest NUCLEO-WB55 offers a more efficient design, ST updated the P-NUCLEO-WB55 with the new board.

    The NUCLEO-WB55RG and Its Ecosystem

    The new NUCLEO-WB55RG represents the next step for developers. After working with the P-NUCLEO-WB55 and running a proof-of-concept, the new board will help them get closer to their final application. For instance, engineers can use the X-NUCLEO-LPM01A, a shield that measures power consumption, or X-CUBE-CLKTRIM, a software tool that helps with the crystal oscillator trimming to improve the RF performance in Bluetooth. Similarly, teams can also use STM32CubeMonitor-RF to test the performance of their radio.
