{"title":"SparkFun microSD Shield","handle":"sparkfun-microsd-shield","url":"/products/sparkfun-microsd-shield","description":"The SparkFun microSD Shield gives your Arduino mass-storage capability via a microSD card slot, making it ideal for data-logging and projects that need to read or write files.\n\nCommunication with the microSD card uses the SPI interface. The SCK, DI, and DO pins connect to the ATmega168/328's standard SPI pins (digital 11–13), while the chip select (CS) pin is routed to digital pin D8. A large 13×12 prototyping area with 0.1″ pitch plated through-holes provides plenty of space for additional circuitry.\n\nKey Features\n\n\nmicroSD Card Slot – Add removable mass storage to any Arduino project\n\nSPI Interface – Uses digital pins 11–13 for SPI, D8 for chip select\n\nPrototyping Area – 13×12 grid of 0.1″ pitch PTHs for custom circuitry\n\nPower LED – Red indicator confirms the shield is powered\n\nReset Button – Convenient on-board reset access\n\n\n\nNote: Most Arduino SD/FAT libraries (such as FAT16 or SDFat) default to CS on pin D10. You will need to change the CS pin to D8 in your code and set D8 as an output in your setup() function.\n\n\nIdeal For\n\nData logging (sensor readings, GPS tracks, environmental monitoring)\nFile storage and retrieval on Arduino projects\nPrototyping with the built-in PTH grid\n\n\nPackage Contents\n\n1× SparkFun microSD Shield (headers not included — see the Arduino Stackable Header Kit)\n\n\nResources\n\nHookup Guide\nGitHub Repository\n","vendor":"SparkFun","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":12966,"title":"Default Title","sku":"SF-DEV-12761","price":35.24,"on_sale":false,"in_stock":true,"available_quantity":5,"option1":"Default Title"}]}
