The SD card reader module for Arduino and ARM MCU makes it possible to connect an SD memory card or a Micro SD card to a microcontroller board. It can both read from and write to the card, and it fits all Arduino boards.
The module is easy to install as a peripheral on the sensor shield of an Arduino, and it exposes the SPI contacts you need: MOSI, SCK, MISO and CS.
It runs from 3.3V or 5V, so it works with common 3.3V ARM boards and 5V Arduino boards.
SD and Micro SD support: connects a memory card to a microcontroller.
Read and write: the Arduino can both read and write to the card.
3.3V / 5V input: works with common board voltages.
SPI interface: the necessary contacts for SPI: MOSI, SCK, MISO and CS.
Easy installation: plugs in as a peripheral to an Arduino sensor shield.
An SD card module connects to a microcontroller through the SPI bus, which uses four signal wires: a clock (SCK), data out from the microcontroller (MOSI), data in (MISO) and a chip-select line (CS). Software libraries provide a file system, so that your program can create, read and append to files just like on a computer.
This is useful for data logging: a sensor project can write a line of measurements to a file every second and you can later read the file on a computer. For reliable logging, use a good quality card formatted as FAT32, keep the card seated firmly and close files properly so that data is not lost when power is removed.
When you use a 5V board with a 3.3V card interface, make sure the module's level shifting suits your board, as the card itself is a 3.3V device.
