SD Card Reader breakout board/module SPI
Product information:
This Arduino SD Card module is a simple solution to read/write data from/to a standard SD card.
The pinout is directly compatible with the Arduino but this module can also be used with other microcontrollers.
This allows you to add mass storage and data logging to your project.
Suitable for SD and SDHC cards (not included).
Easy to connect according to the pinout below.
With the SD card library and programming examples included in the Arduino software, you can get started right away!
Voltage: 3.3V
Output/input: SPI pins; MOSI, SCK, MISO and CS
Pins Arduino <=> Module:
10 - CS /SS (chip select)
11 - MOSI
12 - MISO
13 - SCK / CLK
5V - 5V or 3.3V - 3.3V
GND - GND
Pins Arduino Mega <=> Module:
50 - MISO
51 - MOSI
52 - SCK / CLK
53 - CS/SS (chip select)
5V - 5V or 3.3V - 3.3V
GND - GND
In your Arduino sketch you indicate that you use pin 10 (Mega 53) for chip select.
NB!
The Arduino gives 5V signals while the signals for the reader must be 3.3V. Connect it according to the diagram in the pictures.
