Please note that there looks to be two variants of MCUDev DevEBox STM32H7XX_M boards with different chips / flash memory.

MCUDev DevEBox STM32H7XX_M with STM32H750VBT6 (128KB flash memory & 1024KB SRAM)

MCUDev DevEBox STM32H7XX_M with STM32H743VIT6 (2048KB flash memory & 1024KB SRAM)

note that the variant made for WeAct MiniSTM32H743VITX would likely work for MCUDev DevEBox STM32H743VIT6
#1552
As it uses 25 Mhz HSE crystal same on both boards.
However, do note that the symbols LED_BUILTIN and USER_BTN are different between the 2 boards.
To use the WeAct variannt for MCUDev DevEBox STM32H743VIT6, avoid using the 2 symbols or re-define them in your arduino sketch. you could also simply clone the WeActH743VITX variant file and make mods locally e.g. make a new variant if you prefer.
