(Board designer) YXZhu's version: https://github.com/YXZhu/micropython/tree/master/ports/stm32/boards/WeAct_F411CE

My slightly modified version: https://github.com/mcauser/WEACT_F411CEU6

Perhaps we should combine our efforts?

YXZhu also has a F401 board:

Yes please! Is there a reason why @YXZhu did not create a PR for this board?

I had too many things to do and was afraid I wouldn't have time to maintain micropython so I didn't create a PR.

I've just updated and tested this with the external flash, it should be ready for merging now. It's based on the work linked above (and the source repos are linked in the header).

@mcauser there is an issue in your repo, for the V2.0 board the SPI flash MISO is connected to PB4.

@YXZhu is there a reason why the SPI flash was changed from PA6 to PB4?

The SDIO peripheral has a SDIO_CMD pin in PA6. If the Flash USES PA6, the SDIO cannot be used. Later, considering that we seldom USES the SDIO peripheral, the V2.1+ version of Flash re-uses PA6

Ok thanks, that makes sense. I just found the schematics too: https://github.com/WeActTC/MiniF4-STM32F4x1

And I see there is now a v2.2, but it doesn’t seem to be available on aliexpress yet. I will have to keep an eye out for them.

Is this still useful/interesting to merge?

@mcauser would it make your repo for this board obsolete?

I think this is still useful (I still use it), are there any changes that need to be made for it to be merged?

are there any changes that need to be made for it to be merged?

If you could rebase on master that would be a good start.

Closing due to inactivity. Feel free to reopen with board.json and images if the board is still relevant and in production.
