The last post people are talking about issues with the current solution - I want to start a little opensource project designing a breakout for this, I can label all the pins and incorporate whatever else would be useful, LEDs, sensors, headers, etc...

Seeed can manufacture PCBs that are 0.6mm & 0.8mm, I believe a post above said they must not be thicker than 0.75mm, but the height of a uSD card is ~1mm - would the 0.6mm or 0.8mm be best?


I can also send out some free board for people. They'll be dirt cheep.

Let me know if anyone is interested in helping out (feedback, suggestions, etc...) we can set up a time on the IRC

I'm definitely interested in providing input !   Wink

I think .8mm  would be pressing it;  but, really,  the best way to spec the end of the board is that it should look and be precisely identical (exactly) with a micro SD card !  --not thicker,  not thinner;

Also, it needs to be able to activate the spring latch correctly of a push-push slot like the one in the Pinebook.

The Sparkfun board works but is sloppy in both regards to the above two requirements.  The other brand does not work at all because its too thick to enter the slot... it won't even enter the slot of a carrier outside the Pinebook !
