Micro SD Card Reader Module SPI

The Micro SD Card Reader Module adds removable storage to your microcontroller projects, letting you read and write files on a standard Micro SD card through a simple SPI connection. It is perfect for data logging, sensor recording, audio playback, image storage, and any project that needs far more memory than the microcontroller itself offers.

An onboard level shifter and 3.3V voltage regulator let you power the module from 4.5V to 5.5V and connect it to both 5V and 3.3V logic boards, such as Arduino Uno and ESP32. It supports Micro SD cards up to 2GB and Micro SDHC cards up to 32GB, and works with FAT16 and FAT32 file systems through the standard Arduino SD library. Only six pins are needed (GND, VCC, MISO, MOSI, SCK, and CS), and the spring-loaded push-push card slot makes inserting and removing cards quick and easy. Four mounting holes let you fix the board neatly in place.

Whether you are logging temperature data, building a simple music player, or storing configuration files for a larger project, this module is a simple and dependable way to add storage with minimal wiring.
