STM32 NUCLEO-H503RB MB1814A?

[sallen]

In a contest, which is sponsered by ST, I get the NUCLEO-H503RB MB1814A, which seems like a testing product without mass production. Is it possible to get its block diagram of hardware? Why I ask this is that I may face the problem like its HSE is not working.
