Description

The X-NUCLEO-WB05KN1 expansion board provides Bluetooth® Low Energy connectivity for developer applications and can be plugged into an STM32 Nucleo development board (for example NUCLEO-U575ZI-Q) through its ARDUINO® Uno V3 connectors.

The expansion board features Bluetooth® v5.4 compliant and FCC‑certified STM32WB05KN. This SoC manages the complete Bluetooth® Low Energy stack and protocols on its Arm® Cortex®‑M0+ core and programmable flash memory. STM32WB05KN supports central and peripheral modes and increased transfer rates with data length extension (DLE).

X-NUCLEO-WB05KN1 interfaces with the STM32 Nucleo microcontroller via UART (default) with and without hardware flow control. Full duplex SPI with an interrupt line is also available. The firmware loaded on the module defines the host interface and, to modify it, simply change the firmware without modifying the hardware.

  • All features

    • Based on STM32WB05KN with preloaded network coprocessor firmware with UART interface
      • Bluetooth® v5.4 compliant
      • Bluetooth® Low Energy data packet length extension
    • Embedded MLPF-NRG-01D3 integrated impedance matching network with harmonics filter
    • On-board PCB antenna
    • SPI interface optional through dedicated firmware
    • Compatible with STM32 Nucleo boards
    • Equipped with ARDUINO® Uno V3 expansion connector
    • Scalable solution, capable of cascading multiple boards for larger systems
    • Free comprehensive development firmware library and examples, compatible with the X-CUBE-WB05N expansion software package for STM32Cube
