USAGE INSTRUCTIONS
1. Connect the module to your microcontroller's hardware SPI pins (CS, SCK, MOSI, MISO).
2. Power the module by connecting the VCC and GND pins to a 3.3V or 5V supply from your main board.
3. Securely insert a FAT16 or FAT32 formatted Micro SD or TF card into the socket.
4. Utilize a standard SD card library for your development environment (.g., the SD library in the Arduino IDE) to initialize and access the card for reading and writing data.
APPLICATION SCENARIOS
- Data Logging: Capture and readings, GPS coordinates, or system status information over long periods for IoT and scientific projects.
- Extended Storage: Expand the memory of microcontrollers like the UNO R3 or ESP32 to large assets such as sound files for an audio player, images for a small display, or pages for an embedded server.
- Configuration Management: Load and save device settings or user preferences from an SD card, allowing for easy updates and personalization without reprogramming the microcontroller.
- Bootloader or Firmware Storage: Use as a source for firmware updates on field-deployed devices.
WIDE MICROCONTROLLER COMPATIBILITY: Designed to seamlessly integrate with a variety of development boards. Fully with popular AVR microcontroller boards including the UNO R3, MEGA 2560, and Due. Also works excellently with ESP32 and RP2040-based platforms, making it a versatile choice for your data storage needs.
FLEXIBLE POWER & SPI INTERFACE: Features a standard 6-pin SPI interface (CS, SCK, MOSI, MISO, VCC, GND) for straightforward connection. An onboard voltage regulator and logic level shifter allow the module to operate safely with both 3.3V and 5V systems, eliminating the need for external level conversion components.
RELIABLE EXTERNAL DATA STORAGE: Easily add high-capacity, removable storage to your projects. Ideal for applications like data logging from sensors, storing configuration files, saving user settings, or playing audio and image files, preserving your microcontroller's limited internal flash memory.
COMPACT AND READY TO USE: This lightweight and compact module is designed to fit easily into any project enclosure. Each board comes with a pre-soldered 6-pin header, allowing for immediate connection to your microcontroller or breadboard without any soldering required.
ONBOARD LEVEL SHIFTER FOR ROBUST PERFORMANCE: The integrated chip level conversion ensures stable and reliable communication between the 3.3V logic level of the SD card and the host microcontroller, whether it operates at 3.3V or 5V. We provide comprehensive after-sales : complete digital documentation including user guides and technical references is available through , and our team is ready to assist with installation, programming, and troubleshooting to help you started quickly.
