SparkFun microSD Shield [DEV-12761] - (AD15530)

Description:

Are you running low on memory in your Arduino project? The SparkFun microSD Shield gives your Arduino mass storage capability, allowing you to use it for data logging or other related projects.

Communication with microSD cards is done using an SPI interface. The SCK, DI, and DO pins of the microSD socket connect to the standard ATmega168/328 SPI pins (digital 11-13), while the CS pin connects to Arduino pin D8. If you choose to use one of the many open-source FAT libraries (such as FAT16 or SDFat), make sure to modify the code to reflect the location of the CS pin.

Most libraries assume the CS pin is connected to D10; this will need to be changed to D8. Additionally, for the libraries to work, pin D8 will need to be configured as an output in the “setup()” section of your program. The shield also includes a large prototyping area with a 13x12 grid of 0.1" pitch PTHs.

This shield includes a microSD slot, a red power indicator LED, and a reset button; however, it does not include headers. We recommend the Arduino R3 Stackable Header Kit.
