Hello!
I use Arduino mega 2560 and sd module: Boost - Buy In Coins
My sd card:
I connect sd module to mega:
5v -> 5v
cs -> 53
mosi -> 51
sck -> 52
miso -> 50
connection:
code:
/*
* This sketch attempts to initialize an SD card and analyze its structure.
*/
#include <SdFat.h>
/*
* SD chip select pin. Common values are:
*
* Arduino Ethernet shield, pin 4.
* SparkFun SD shield, pin 8.
* Adafruit SD shields and modules, pin 10.
* Default SD chip select is the SPI SS pin.

I formatted sd card with SD Memory Card Formatter for Windows/Mac | SD Association or standart windows 7 utility.
But this dont work! I get an error when receiving the card format:
init time: 3 ms
Card type: SD2
Manufacturer ID: 0X74
OEM ID: JE
Product: SDC
Version: 1.0
Serial number: 3003785441
Manufacturing date: 5/2013
cardSize: 1966.08 MB (MB = 1,000,000 bytes)
flashEraseSize: 128 blocks
eraseSingleBlock: true
SD Partition Table
part,boot,type,start,length
1,0X0,0X6,137,3839863
2,0X0,0X0,0,0
3,0X0,0X0,0,0
4,0X0,0X0,0,0
vol.init failed
SD errorCode: 0X4
SD errorData: 0XFF
So, this module can be thrown out? Or this module can be corrected?
