ST Nucleo L412KB

Contents

Hardware

Platform :ref:`platform_ststm32`: 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 STM32L412KBU6
Frequency 80MHz
Flash 128KB
RAM 40KB
Vendor ST

Configuration

Please use nucleo_l412kb ID for :ref:`projectconf_env_board` option in :ref:`projectconf`:

[env:nucleo_l412kb]
platform = ststm32
board = nucleo_l412kb

You can override default ST Nucleo L412KB settings per build environment using board_*** option, where *** is a JSON object path from board manifest nucleo_l412kb.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:nucleo_l412kb]
platform = ststm32
board = nucleo_l412kb

; change microcontroller
board_build.mcu = stm32l412kbu6

; change MCU frequency
board_build.f_cpu = 80000000L

Uploading

ST Nucleo L412KB supports the following uploading protocols:

  • blackmagic
  • cmsis-dap
  • jlink
  • stlink

Default protocol is stlink

You can change upload protocol using :ref:`projectconf_upload_protocol` option:

[env:nucleo_l412kb]
platform = ststm32
board = nucleo_l412kb

upload_protocol = stlink

Debugging

:ref:`piodebug` - "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 :ref:`debugging_tools` using :ref:`projectconf_debug_tool` option in :ref:`projectconf`.

ST Nucleo L412KB has on-board debug probe and IS READY for debugging. You don't need to use/buy external debug probe.

Compatible Tools On-board Default
:ref:`debugging_tool_blackmagic`    
:ref:`debugging_tool_cmsis-dap`    
:ref:`debugging_tool_jlink`    
:ref:`debugging_tool_stlink` Yes Yes

Frameworks

Name Description
:ref:`framework_arduino` Arduino Wiring-based Framework allows writing cross-platform software to control devices attached to a wide range of Arduino boards to create all kinds of creative coding, interactive objects, spaces or physical experiences.
:ref:`framework_cmsis` Vendor-independent hardware abstraction layer for the Cortex-M processor series
:ref:`framework_stm32cube` STM32Cube embedded software libraries, including: The HAL hardware abstraction layer, enabling portability between different STM32 devices via standardized API calls; The Low-Layer (LL) APIs, a light-weight, optimized, expert oriented set of APIs designed for both performance and runtime efficiency
