SD Memory Card Reader Writer Module with SPI Interface for Arduino

Key item features

  • ‌Full-Sized SD Card Slot: Spring-loaded push-push slot accepts standard SD cards (up to 2GB) and SDHC cards (up to 32GB). Ideal for data logging, file storage, and configuration management in microcontroller projects.
  • Dual Voltage Power Input: Separate 3.3V and 5V power input pins let you connect directly to either 5V microcontrollers like Arduino Uno or 3.3V boards like ESP32. Connect only one power pin — never both at the same time.
  • Onboard Level Shifting: Built-in level-shifting circuitry safely translates logic signals between your microcontroller's voltage level and the 3.3V levels required by the SD card. No external level shifter needed.
  • Standard SPI Interface: Communicates using the standard SPI bus (MOSI, MISO, SCK, CS) for fast and reliable data transfer. Compatible with the built-in Arduino SD library — no extra libraries required.
  • Breadboard Friendly Design: Header pins on standard 2.54mm pitch plug directly into a breadboard. Also works with female Dupont-style jumper wires for flexible project wiring.
  • LED Status Indicators: Onboard power LED and activity LED let you confirm the module is receiving power and actively communicating with the SD card during read/write operations.
  • Write-Protect Support: Full-sized SD cards include a physical write-protect switch on the side of the card, allowing you to prevent accidental data overwrites in your projects.
  • Arduino Library Compatible: Works out of the box with the Arduino IDE's built-in SD library. Create, read, write, and delete files and directories on the SD card with simple Arduino code.
