Standard micro SD card slot?
« on: March 02, 2020, 02:34:40 am »
On web sites like Aliexpress or ebay you can often find standard, jellybean parts being sold by many vendors.  For example, you can get things like USB connectors or PCB barrel jacks that have a common footprint so that you can be reasonably sure that designs using them can be easily replicated and parts easily replaced in the future. 

Are there any PCB SD, or preferably microSD, card slots that have common footprint?  If anyone has any experience with a particular card slot that you could point me to, that would be helpful. I am hoping to find something not overly cheap as to survive multiple insertion cycles.

Perhaps what I am looking for does not exist but if you know of any, please point them out.  Thanks!

This one seems to be the most common:
942070-0

https://lcsc.com/products/Card-Sockets-Connectors_637.html filter by card type "microsd memory card" and sort by availability. The top few ones all have the same footprint.

This is the one that I install in my products, and it works very well. At 0.05 USD/pcs, from Chinese vendors.

I think it is quite standard, because I have already bought it from several suppliers, and with small variations, but the footprint for the PCB is the same.

Ok, I can get some of this card type with my next JLCPCB order.  Thanks all for your suggestions.
