Micro SD Card Module for Arduino

Micro SD Card Module for Arduino — SPI Interface

This micro SD card module adds mass storage to any Arduino or ESP32 via 4-wire SPI, letting you log sensor data to a FAT16 or FAT32-formatted card and read it back on a PC without special hardware. The onboard level shifter converts 5V SPI signals to 3.3V for the card interface, and the module works at SPI speeds up to 25MHz. The Arduino SD library handles all card communication including file create, write, read, and delete.

• Micro SD card slot — FAT16 and FAT32 formatted cards up to 32GB
• SPI interface — MOSI, MISO, SCK, CS
• Onboard level shifter — 5V logic in, 3.3V to card
• 3.3V–5V supply — compatible with Arduino and ESP32
• Compatible with Arduino SD library — no extra libraries needed

Best for

Arduino sensor data logging, GPS track recording, audio playback (with DFPlayer), configuration file storage, image loading for TFT displays, and any project needing persistent storage beyond EEPROM capacity.
