Key Benefits

The most complete platform for prototyping your Wireless applications

STM32WB5MM-DK contains a rich set of functionalities including MEMS sensors from STMicroelectronics, OLED display, digital microphone, gesture detection sensor, users leds/buttons, external flash and flexible power supply options.

An excellent reference Hardware for design development and testing

Test RF performance, power consumption, and integration with other boards and components using STM32WB5MM-DK. Also serves as a reference design with many resources. Open hardware platform.

Open Hardware platform and including many resources

STM32WB5MM-DK is an open hardware platform supporting several IDEs such as IAR Embedded Workbench®, MDK-ARM, and STM32CubeIDE. It also comes with many online resources including ST Wiki and CubeFW.


The STM32WB5MM-DK Discovery kit is designed as a complete demonstration and development platform for the STMicroelectronics STM32W5MMG module based on the Arm® Cortex®-M4 and Arm® Cortex®-M0+ cores.

The STM32 device is a multi-protocol wireless and ultra-low-power device embedding a powerful and ultra-low-power radio compliant with the Bluetooth® Low Energy (BLE) SIG specification v5.2 and with IEEE 802.15.4-2011.

The hardware features of the Discovery kits are available for users to develop their applications: Audio, USB, user buttons, and Bluetooth® Low Energy. Extension connectors allow easy connection of an ARDUINO® board for a specific application.

An ST-LINK/V2-1 is integrated on the board, as an embedded in-circuit debugger and programmer for the STM32 MCU and the USB Virtual COM port bridge.
