Nucleo G431KB

Hardware

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 STM32G431KBT6
Frequency 24MHz
Flash 128KB
RAM 32KB
Vendor ST

Configuration

Please use nucleo_g431kb ID for board option in “platformio.ini” (Project Configuration File):

[env:nucleo_g431kb]
platform = ststm32
board = nucleo_g431kb

You can override default Nucleo G431KB settings per build environment using board_*** option, where *** is a JSON object path from board manifest nucleo_g431kb.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:nucleo_g431kb]
platform = ststm32
board = nucleo_g431kb

; change microcontroller
board_build.mcu = stm32g431kbt6

; change MCU frequency
board_build.f_cpu = 24000000L

Uploading

Nucleo G431KB supports the next uploading protocols:

  • blackmagic
  • jlink
  • mbed

Default protocol is mbed

You can change upload protocol using upload_protocol option:

[env:nucleo_g431kb]
platform = ststm32
board = nucleo_g431kb

upload_protocol = mbed

Debugging

PIO Unified Debugger - “1-click” solution for debugging with a zero configuration.

Warning

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).

Nucleo G431KB does not have on-board debug probe and IS NOT READY for debugging. You will need to use/buy one of external probe listed below.

Compatible Tools On-board Default
Black Magic Probe   Yes
J-LINK
