SDio add-on?

I read that there is an SDIO add on card for the 407 Discovery card. Can somebody give a link to it. I could clone the board and code.

Is this current? From Clive1.

For the STM32F4-Discovery I've migrated to the configuration used by the

break-out board. I've updated the code I use, and have newer versions of FatFs. There are also more recent boards like the

and

that come with MicroSD slots directly on board. The code tends to need tailoring to the specific GPIO being used to detect the cart in the socket for a particular board design.

Very good. Thanks.

Edit: We need video capabilities too. And there seems to be display and video cap. too on that board. Is the board fast in decoding the video. Could it drive a larger display.

The F407 is probably a poor choice for video/camera use cases. The newer F7 and F4 parts have better display handling characteristics. Video decode is something that needs efficient codecs, especially with high resolutions or frame rates, not something I think the Cortex parts are well suited. The new F7 has a JPEG codec.
