eMMC prototyping on NUCLEO

[frd66]

Hi All,

I'm looking for advices about boards/components to use for eMMC prototyping.

I have got a NUCLEO-H743ZI board, but it seems that there is no shield board for eMMC, and that a solution would be to use SD/MMC card breakout + eMMC dongle.

Could one give me some references?

Or confirm that those:

• SparkFun SD/MMC Card Breakout
• eMMC Module Reader Board
• 16GB eMMC Module

are OK?

Thanks in advance!

Hours of fun to be had there.. My approach was to use the ODROID eMMC modules, will also plug directly into an assortment of EVAL and DISCO series boards. Have 4 thru 128 GB working.

People have made direct dongles, but soldering eMMC BGA's is a pain. For raw devices consider clam-shell sockets.

These would be better sockets, having appropriate pull-ups and size

I have some direct ones that plug in the back-side of the Nucleo-144 also.

Thanks for the answer, Clive.

Seems more difficult to purchase from here (France), but I will try anyway...

What do you mean by 'I have some direct ones that plug in the back-side of the Nucleo-144 also.' ?

Another reference?
