Breakout Board for microSD Transflash

Introduction

Breakout board for the microSD socket that is not much bigger than your fingernail.

Compatible with the SPI interface found on any SD card, this tiny form factor was created for cell phone storage and is perfect for your next 3D printer project!

Board comes fully assembled and tested.The bare socket is available.

Features

• SPI mode
• Support voltage:3.0 to 3.6V
• Up to 50 MB/sec data transfer rate
• Sits directly on a Arduino
• Also be used with other microcontrollers

Usage

1.Sometime you're not sure whether a card is working or not,you must test it.

Now,let's go.

Example code

Open Files ->Examples ->SD ->Cardinfo

// include the SD library:
#include <SD.h>
// set up variables using the SD utility library functions:
Sd2Card card;
SdVolume volume;
SdFile root;
// change this to match your SD shield or module;
// Arduino Ethernet shield: pin 4
// Adafruit SD shields and modules: pin 10
// Sparkfun SD shield: pin 8
const int chipSelect = 4;    
void setup()
{
 // Open serial communications and wait for port to open:
 Serial.begin(9600);
  while (!Serial) {
   ; // wait for serial port to connect. Needed for Leonardo only
 }
Serial.print("\nInitializing SD card...");
// On the Ethernet Shield, CS is pin 4. It's set as an output by default.
// Note that even if it's not used as the CS pin, the hardware SS pin 
// (10 on most Arduino boards, 53 on the Mega) must be left as an output 
// or the SD library functions will not work. 
pinMode(10, OUTPUT);     // change this to 53 on a mega
// we'll use the initialization code from the utility libraries
// since we're just testing if the card is working!
if (!card.init(SPI_HALF_SPEED, chipSelect)) {
Serial.println("initialization failed. Things to check:");
Serial.println("* is a card is inserted?");
Serial.println("* Is your wiring correct?");
Serial.println("* did you change the chipSelect pin to match your shield or module?");
return;
 } else {
Serial.println("Wiring is correct and a card is present."); 
 }
// print the type of card
Serial.print("\nCard type: ");
switch(card.type()) {
   case SD_CARD_TYPE_SD1:
     Serial.println("SD1");
     break;
   case SD_CARD_TYPE_SD2:
     Serial.println("SD2");
     break;
   case SD_CARD_TYPE_SDHC:
     Serial.println("SDHC");
     break;
   default:
     Serial.println("Unknown");
 }
// Now we will try to open the 'volume'/'partition' - it should be FAT16 or FAT32
if (!volume.init(card)) {
   Serial.println("Could not find FAT16/FAT32 partition.\nMake sure you've formatted the card");
   return;
 }
 // print the type and size of the first FAT-type volume
 uint32_t volumesize;
 Serial.print("\nVolume type is FAT");
 Serial.println(volume.fatType(), DEC);
 Serial.println();
 volumesize = volume.blocksPerCluster();    // clusters are collections of blocks
 volumesize *= volume.clusterCount();       // we'll have a lot of clusters
 volumesize *= 512;                            // SD card blocks are always 512 bytes
 Serial.print("Volume size (bytes): ");
 Serial.println(volumesize);
 Serial.print("Volume size (Kbytes): ");
 volumesize /= 1024;
 Serial.println(volumesize);
 Serial.print("Volume size (Mbytes): ");
 volumesize /= 1024;
 Serial.println(volumesize);
 Serial.println("\nFiles found on the card (name, date and size in bytes): ");
 root.openRoot(volume);
 // list all files in the card with date and size
 root.ls(LS_R | LS_DATE | LS_SIZE);
}
void loop(void) {
 
}

Open Serial Monitor

OK,the card is working.

2.You can connect the microSD transflash to 3D printer（Sanguinololu and Teensylu).
