SD Card Reader SPI Module

SD Card Reader SPI Module

Add gigabytes of removable storage to your project with this robust SD Card Reader Module. Designed for standard-sized SD cards, this module is an essential component for projects that require large-scale data logging, file storage, or configuration management. It allows your microcontroller to read and write files just like a computer.

This module communicates using the common SPI (Serial Peripheral Interface) protocol, making it widely compatible with microcontrollers like Arduino, ESP32, and others. It features an onboard 3.3V regulator and logic level shifters, allowing it to be safely powered and controlled by both 5V and 3.3V systems. This built-in voltage regulation protects your SD card from damage when used with 5V microcontrollers like the Arduino Uno.

With a standard pinout and a full-size SD card socket, this module is ready to be integrated into your next data-intensive project, whether it’s for a weather station, a robotics platform, or an interactive display.

Key Features:

• Interface: Standard SPI (MOSI, MISO, SCK, CS).
• Voltage Compatibility: Safely works with both 5V and 3.3V power and logic, thanks to an onboard regulator and level shifters.
• Card Format: Supports standard SD and SDHC cards.
• Easy to Use: Standard header pins for easy connection to breadboards and microcontrollers.
• Secure Socket: Full-size SD card socket holds the card firmly in place.

Applications:

Perfect for creating a powerful data logger to record sensor readings over long periods, storing images and fonts for graphical displays, saving user settings and configuration files, or any project that needs more memory than the microcontroller’s onboard flash can provide.
