Posted On July 6, 2019 at 10:43 am by / Comments Off on Micro SD Card Module for Arduino

Size4.1 x 2.4cm
Power supply4.5V to 5.5V, 3.3V voltage regulator circuit board
Communication interfaceStandard Spi Interface
SupportsMicro Sd Card (more Than Equal To 2g), Micro Sdhc Card (less Than Equal To 32g) (high-speed Card)
Control InterfaceA total of six pins (GND, VCC, MISO, MOSI, SCK, CS)


  • Onboard 5v->3v regulator provides 150mA for power-hungry cards
  • 3v level shifting means you can use this with ease on either 3v or 5v systems
  • Uses a proper level shifting chip, not resistors: less problems, and faster read/write access
  • Use 3 or 4 digital pins to read and write 2Gb of storage!
  • Activity LED lights up when the SD card is being read or written
  • Four #2 mounting holes
  • Push-push socket with card slightly over the edge of the PCB so its easy to insert and remove
  • Comes with 0.1″ header (unattached) so you can get it on a breadboard or use wires – your choice
  • Tested and assembled here at the Adafruit factory
  • Works great with Arduino, with tons of example code and wiring diagrams

To use with an Arduino, connect GND to ground, 5V to 5V, CLK to pin 13, DO to pin 12, DI to pin 11, and CS to pin 10. Then you can use the Arduino IDE’s SD library which supports FAT and FAT32 SD cards
