STMICROELECTRONICS NUCLEO-WB05KZ Development Board

The STM32 NUCLEO-WB05KZ development board enables easy evaluation and development of Bluetooth Low Energy wireless applications. Powered by the ultra-low-power STM32WB05KZ MCU based on the Arm Corter-M0+ core, it features an integrated 2.4 GHz RF transceiver compliant with Bluetooth v5.4 and a built-in PCB antenna. The board includes Arduino Uno V3 and ST Morpho headers for flexible expansion and full access to MCU I/Os. With an on-board STLINK-V3EC debugger, USB Type-C connectivity, and STM32CubeWB software support, it accelerates the development of wireless IoT and embedded applications. Features: STM32WB05KZ ultra-low-power wireless MCU Bluetooth Low Energy v5.4 compliant radio Built-in PCB antenna for RF connectivity Arduino Uno V3 and ST Morpho expansion headers On-board STLINK-V3EC debugger/programmer Core Architecture: Arm Cortex-M0+ (32-bit) ntenna Type: Integrated PCB antenna (on-board RF trace antenna; typical gain ~0 dBi, refer to RF layout documentation for exact value) BLE Stack Support: Supported via STM32CubeWB software package and STM32Cube ecosystem Package Includes: 1 x STMICROELECTRONICS NUCLEO-WB05KZ Development Board
