Create tons of storage space for your Arduino with this is the just-launched SD card V4.0 shield. Letting you read/write an SD card via Arduino’s built-in SD library, this device also works seamlessly with SD, SDHC and Micro SD cards. Better still, it will only occupy your Arduino’s SPI port. Bringing together the standard SD and Micro SD slots in a single standard one, the device comes with an adaptor to let you use Micro SD cards. Stack on other shields that operate with the unused pins or opt for the preformed I2C and UART port to enable you to link up to Grove modules.
