Help with an SD Card Reader for the Arduino

I am looking for some help with an SD Card Reader for the Arduino. We bought several of the SD-MMC Breakout SD Card Readers from Sparkfun.

Product link: https://www.sparkfun.com/products/12941

We aren't able to find a connection guide for it, and we are having a problem with getting it to work. Is anyone familiar with this product, and how we might hook it up.

Any help or previous experience would be greatly appreciated!

Hi mikedavis - I'm not familiar with this particular board, but have some experience with other sd card break out boards.and Arduino

Some indication of what you've tried so far would be helpful.

Meanwhile, this looks usefull: https://www.sparkfun.com/products/retired/204
in that it identifies which pins seem to be relevant and links further to https://www.maximintegrated.com/en/app-notes/index.mvp/id/3969
which shows the connections quite clearly in figure 1

Hope this helps

Neil

Rather than look for data on the SD card socket, look for data regarding the actual SD card. refering to the schematics provided by sparkfun, it is clear the card does nothing except pass the singnals from the arduino to the SD card. so you need to look up how to use an arduino or other mucrocontroller to talk to the SD card

for example... here: Tutorial How to use SD Card with Arduino - GarageLab (arduino, electronics, robotics, hacking) or here: How To: Connect Your Old SD Card To An Arduino - Martin Gardner.co.uk

I performed a simple google to find these on the first page of the results.
Hope it helps

Thanks Peter! We got it working, but it came down to the SD cards themselves. The Kingston ones we got from Sparkfun weren't working the reader, so I had to get new ones.
