Micro SD Card Module for Arduino 3 4 Channel Relay Module 5VThe Arduino Micro SD Card Module is a Micro SD card reader module that utilizes both the file system and the SPI interface driver. Through this integrated system, the SCM (System Control Module) completes the tasks of reading and writing to the MicroSD card. Arduino users can conveniently employ the built in SD card library in the Arduino IDE for seamless card initialization and reading. Highlights: Support for MicroSD Card and Micro SDHC Card (high
