Micro SD Shield

Micro SD Shield

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 13×12 grid of 0.1″ pitch PTHs.

This shield comes populated with a microSD socket, red power indicator LED, and a reset button; but it does not come with headers installed. We recommend the 6 and 8-pin stackable headers.
