Description: This is the same product as the microSD Shield but also includes the headers. This version comes in fancy clamshell packaging meant for our distributors that need it. Regular customers are welcome to order, but we want to limit the amount of extra packaging finding its way into the trash heap. A microSD quickstart guide is available!

Running out of memory space in your Arduino project? The microSD Shield equips your Arduino with mass-storage capability, so you can use it for data-logging or other related projects.

Communication with microSD cards is achieved over an SPI interface. The SCK, DI, and DO pins of the microSD socket are broken out to the ATmega168/328’s standard SPI pins (digital 11-13), while the CS pin is broken out to Arduino’s D8 pin. If you decide to use one of the many open source FAT libraries (like FAT16 or SDFat) make sure to change the code to reflect the location of the CS pin. Most libraries assume the CS pin is connected to D10; this will have to be changed to D8. Also for the libraries to work pin D10 will have to be set as an output in the ‘setup()’ section of your sketch. The shield also includes a large prototyping area with a 13x12 grid of 0.1" pitch PTHs.

Note: This product does not come with a microSD card. These cards change in size and price frequently. Check your local electronics retailer for a good deal or you can pick up our standard 1GB microSD card.

  • UPDATE: So I initially had issues getting the MicroCenter MicroSD cards to work…but it turns out the MicroCenter MicroSD cards work fine with the Arduino libaraies; my Ethernet PRO Arduino had issues. These are a GREAT value!

    I picked one of these up at Micro Center this weekend! (Very nice partnership by the way!) Micro Center 2GB Micro SD Media Card )
    Oh and I had to use an extra set of stackable headers for this to clear the magjack on my EthernetPro…Kinda sucky but Im pretty much over it already.

    I have had no issues with this MicroSD Shield!

  • Be sure to use the correct CS pin. The Arduino library should support selecting the custom pin when you initialize the SD card.

  • Trying to connect the MicroSD Shield to a Leonardo but it seem that the Leonardo only has SPI on the ICSP Pins which the MicroSD Shield does not have. Is the Leonardo incompatable?

  • I agree with cap9qd. Purchased one of these shields and no matter what I try it will not work. Check my solder joints and they are good. Change the SS_PIN .. nothing. Reformatted in FAT16, FAT32 .. nothing.
    There is definitely something wrong with the shield and/or the driver(s) (I even tried uFat to see if I could get that to work .. guess what .. nothing).
    I have purchased many items from SparkFun and never had an issue like this.
    Recommendation .. don’t get this .. too many problems.
