Custom STM32 Board using existing Nucleo Debugger

Custom and community boards

I use the boards STM32F429ZI (NUCLEO-F429ZI - STM32 Nucleo-144 development board with STM32F429ZI MCU, supports Arduino, ST Zio and morpho connectivity - STMicroelectronics) and STM32F401RE (NUCLEO-F401RE - STM32 Nucleo-64 development board with STM32F401RE MCU, supports Arduino and ST morpho connectivity - STMicroelectronics). They both have a built in debugger/ST-link.

I plan on making custom boards using the same chip F429ZI /F401RE with the debugger built in the nucleo boards. is it plug and play? or is there anything I need to change on the online compiler to be able to use the custom boards.

Hello Muhammed,

If you install a programmer/debugger onto the custom boards as used on the NUCLEO boards then they become plug&play. But even if you don’t install such programmer/ debugger you can use any NUCLEO board equipped with a programmer/debugger or an ST-Link V2 USB dongle to program and debug your custom boards. For more details have a look at
