DISCO-WB5MMG

Discovery kit with STM32WB5MMG MCU

Overview¶

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
