Some people recommend against using a resistor based circuit but I ran the bench-marking test for the one I built and it runs as good as the SD slot of the official Ethernet shield. A quick hack would be to solder directly onto a microSD adapter to break out the pins.<br />Let me know if I can be of any help with the SD card interface.</p><p>Kevin</p><img src="https://community.element14.com/aggbug?PostID=17585&AppID=115&AppType=Weblog&ContentType=0" width="1" height="1">
