P-Nucleo WB55RG


Platform ST STM32: The STM32 family of 32-bit Flash MCUs based on the ARM Cortex-M processor is designed to offer new degrees of freedom to MCU users. It offers a 32-bit product range that combines very high performance, real-time capabilities, digital signal processing, and low-power, low-voltage operation, while maintaining full integration and ease of development.

Microcontroller STM32WB55RG
Frequency 64MHz
Flash 512KB
RAM 192.00KB
Vendor ST


Please use nucleo_wb55rg_p ID for board option in “platformio.ini” (Project Configuration File):

platform = ststm32
board = nucleo_wb55rg_p

You can override default P-Nucleo WB55RG settings per build environment using board_*** option, where *** is a JSON object path from board manifest nucleo_wb55rg_p.json. For example, board_build.mcu, board_build.f_cpu, etc.

platform = ststm32
board = nucleo_wb55rg_p

; change microcontroller
board_build.mcu = stm32wb55rg

; change MCU frequency
board_build.f_cpu = 64000000L


P-Nucleo WB55RG supports the next uploading protocols:

  • blackmagic
  • cmsis-dap
  • jlink
  • stlink

Default protocol is stlink

You can change upload protocol using upload_protocol option:

platform = ststm32
board = nucleo_wb55rg_p

upload_protocol = stlink


Debugging - “1-click” solution for debugging with a zero configuration.


You will need to install debug tool drivers depending on your system. Please click on compatible debug tool below for the further instructions and configuration information.

You can switch between debugging Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).

P-Nucleo WB55RG has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.
