Micro SD Card Reader Module

The Micro SD Card Reader Module is a compact, SPI-based interface board designed to connect microSD memory cards to microcontrollers and development boards. It provides a convenient way to read from and write to microSD cards, making it ideal for data logging, storage, and file handling in embedded electronics projects.

The module supports standard FAT16 and FAT32 file systems and works seamlessly with most 3.3V and 5V microcontrollers, including Arduino, ESP32, STM32, and Raspberry Pi. It uses the SPI (Serial Peripheral Interface) protocol for fast and stable communication and features onboard voltage regulators and level shifters to protect your microcontroller and SD card from over-voltage damage.

The Micro SD Card Reader Module is commonly used in projects that require storage of sensor data, configuration files, or multimedia content. With an easy-to-use pinout and compatibility with SD libraries in Arduino IDE and other platforms, this module is beginner-friendly and robust for long-term use.
