Thank you @ag123 8-)

I have a similar board from another developer: MCUDev DevEBox STM32H7XX_M the H743VIT6 version.

I am using you work as the basis for a variant for the DevEBok version ;)

That looks like a nice and compact board too ;)
The WeAct one is slightly pricier as I think they fixed an LCD on board (I'm still tryng to get it to work - an ST7735) and made FPC connectors for OV2640 camera. But both boards seem pretty much similar for the features.

I looked at the specs for your board in
https://github.com/mcauser/MCUDEV_DEVEBOX_H7XX_M
It seemed the HSE crystal is the same 25 Mhz, hence I't likely 'just works'.
But if you are searching for clocks settings, you could try the python scripts here:
viewtopic.php?f=41&t=78
I made some modifications to that script and I've attached it here.

I stumbled with the ST7735 currently as I found out that ST7735 uses a *half-duplex* SPI protocol.
The MOSI line is shared for the purpose of transmit and receive, this is really incompatible with even the arduino SPI api if the features are to be used.
And in addition, there seemed to be some problems picking up the correct pin mappings for SPI with my variant. SPI stalls, hang. I've not got time to get around to debug it yet.

And now it is merged. The H750VBT has also be added.
Thanks @ag123 :!:

@fpiSTM do the on board led PE3 blink?
mine didn't. But i'm using makefiles and there could be mix up in symbols. with my other files.
Other things are working fine in the test sketch i used, e.g. usb serial works, ok, ADC and mcu temperature readings are ok.
whetstone benchmark works as expected.
Only the led didn't blink.
i did some checks, the pinmap looks correct.
it's getting late and i'd check that again

Yes it works as expected.
