Micro SD Card Breakout Module
Micro SD কার্ড ব্রেকআউট মডিউল
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
