STM32F401RB (64k RAM. 128k Flash)
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.

Configuration
Please use genericSTM32F401RB ID for board option in “platformio.ini” (Project Configuration File):
[env:genericSTM32F401RB]
platform = ststm32
board = genericSTM32F401RB
You can override default STM32F401RB (64k RAM. 128k Flash) settings per build environment using
board_*** option, where *** is a JSON object path from
board manifest genericSTM32F401RB.json. For example,
board_build.mcu, board_build.f_cpu, etc.
[env:genericSTM32F401RB]
platform = ststm32
board = genericSTM32F401RB
; change microcontroller
board_build.mcu = stm32f401rbt6
; change MCU frequency
board_build.f_cpu = 84000000L
Uploading
STM32F401RB (64k RAM. 128k Flash) supports the following uploading protocols:
blackmagicdfujlinkserialstlink
Default protocol is serial
You can change upload protocol using upload_protocol option:
[env:genericSTM32F401RB]
platform = ststm32
board = genericSTM32F401RB
upload_protocol = serial
Debugging
Debugging - “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).
STM32F401RB (64k RAM. 128k Flash) 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.
