Mini SD Micro SD Card Module

Description

What it is

The Mini SD Card is a compact module for Arduino that allows saving and reading data on microSD. Ideal for projects that require external storage.

Features

• Compatible with Arduino and ESP8266/ESP32
• Compact size for integration into small projects
• Provides SPI interface for data communication

What it is for

Ideally used to create an audio recorder that records data from a microphone on a MicroSD Card. Also useful in applications for collecting and storing large amounts of data, such as video recordings or sensors.

Tutorial: How to use Mini SD Card MicroSD Module

The MicroSD SD Card module is a fundamental tool for projects that require the storage of large amounts of data, such as audio or video recordings. Perfect for beginners and intermediates.

What you need

• Arduino Uno
• Micro SD Card
• Jumpers

Steps

1. Connect VCC of the module to 3.3V of the Arduino
2. Connect GND of the module to GND of Arduino
3. Connect CS of the module to pin 10 of Arduino (check the datasheet for correct configuration)
4. Connect SCK, MISO and MOSI to the respective SPI pins of Arduino (see datasheet)
5. Install a SD library from File > Libraries > Add .ZIP Library
6. Include #include in the code
7. Create a Card object using the function SD.begin(pin_CS_card)
8. Search and open the file with SD.open(file_name, mode) to read or write

Example code

FilesystemCard card = SD.card();
if (!card.init(SD_CARD_SELECT)) {
  Serial.println("Errore durante l'inizializzazione della scheda SD.");
  return;
}
Serial.print("Cartella radice: ");
Serial.println(card.rootDir());

Mini project
