I'm new to ARM, so I want to have a play with them by building a POV globe. It requires 380k_bytes of memory, so I have chosen the STM32H750 as my platform. When I first came across these boards on Ebay for £20, I searched for info about them, and I think I read somewhere that they can't be programmed through the USB, though I notice that they have a CH340C USB-Serial chip on them. If they can't be programmed that way, can program be transported to them on the SD card? I can't find any specifications for them on the web, but on the face of it, they look like a good solution to getting me started on this chip. I think I also read that they can only use one SPI channel, which would be a problem for me - but wherever I read these things, I can't find it again, and I'm not sure exactly what I did read.
Can anybody give an appraisal of these low-cost Chinese STM32H750 boards that are available on Ebay, Alibaba, etc?

All the more reason to spend time on laying good foundations to start.

Think carefully about which forum is appropriate.
Most of this has nothing to do with ARM - you would be better off on the ST forum.

ST's own discovery boards are on that order - and do come with full documentation, support, built-in debugger, etc
Some include SD Card.

Those questions would be far better asked on the ST forum: they are specific to the ST part - nothing to do with ARM.
