Adafruit microSD card breakout board
Not just a simple breakout board, this microSD adapter goes the extra mile - designed for ease of use.
- 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: fewer 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 at the Adafruit factory
- Works great with Arduino, with tons of example code and wiring diagrams
To use with an Arduino, connect:Ā
- GNDĀ to ground
- 5VĀ to 5V
- CLKĀ to pin 13
- DOĀ to pin 12
- DIĀ to pin 11
- CSĀ to pin 10
Then you can use the Arduino IDE's SD library which supports FAT and FAT32 SD cards. For details on getting started, check outĀ AdafruitsĀ detailed tutorial which discusses microSD cards, wiring and how to use this breakout board with an Arduino
