This MicroSD card module allows MicroSD cards to be written and read for applications that create or need access to large quantities of data.
SD cards are commonly used for applications such as temperature logging where the time and temperature are recorded over long periods of time. It can also be used to serve large amounts of data such as graphic images.
This MicroSD card module should be thought of as a raw card slot and operates at 3.3V which is the voltage the MicroSD card operates at. The data lines must be at 3.3V logic levels to prevent damage to the MicroSD card and so this module is best used with 3.3V MCUs. If used with a 5V MCU, external logic level shifters are required for the SPI bus lines to avoid damage.
The data lines have 10K pull-up resistors to 3.3V on the module.
The 3.3V current draw will depend on the card being used with the module. When inactive the card may draw 500uA. When reading the card, 15-30mA is common. Write operations take more current and some cards are reported to require up to 100mA for write operations so this should be taken into consideration for selecting the power source. The Arduino 3.3V power which is typically good for about 30-50mA will typically work OK for reading the card, but may be insufficient for write operations. If you experience writing issues, this is the first thing to check.
The module has a male header installed. The module can be inserted directly into a breadboard which is handy since the pin labeling is visible or female Dupont style jumpers can be used to make connections to it.
1×6 Header
In the example we are using here, we are using the Mega 2560 Pro with level shifters.
Insert a MicroSD card into the module and wire up 3.3V and ground and the SPI pins as follows:
The IDE example program SD/CardInfo is a good way to test the basic setup and card. A slightly pruned down version is shown below.
You may need to change this line of code to match the SPI chip select pin for your MCU: const int chipSelect = 53;
An example output of the program is shown below.
/* SD card test This example shows how use the utility libraries on which the' SD library is based in order to get info about your SD card. Very useful for testing a card when you're not sure whether its working or not. Connect 3.3V power and ground. Connect MOSI to MOSI - pin 11 on Uno, 51 on Mega 2560 Connect MISO to MISO - pin 12 on Uno, 50 on Mega 2560 Connect CLK to CLK - pin 13 on Uno, 52 on Mega 2560 Connect CS to SPI Chip select - Pin 10 on Uno, 53 on Mega 2560 */ // include the SD library: #include <SPI.h> #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; const int chipSelect = 53; void setup() { Serial.begin(9600); } Serial.print("nInitializing SD card..."); // 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.
