Micro SD Card SPI Reader Module for Arduino (5V/3.3V)

Easily add storage and data logging capabilities to your Arduino or microcontroller project with this compact Micro SD Card Reader/Writer Module. Designed for simplicity and compatibility, it's the perfect solution for saving sensor data, storing configuration files, or playing audio files.

The onboard logic level shifter and voltage regulator make it incredibly versatile, allowing you to connect it directly to both 5V systems like the Arduino Uno and 3.3V systems like the ESP32 without any extra components.

Key Features:

• Broad Compatibility: Works seamlessly with both standard Micro SD and high-speed Micro SDHC cards.
• Onboard Level Shifter: Safely connects to 5V microcontrollers (e.g., Arduino Uno) as well as 3.3V systems (e.g., ESP32, Raspberry Pi Pico) thanks to the integrated logic level conversion chip.
• Stable 3.3V Power: Features an onboard voltage regulator, allowing you to power the module from a 4.5V to 5.5V source (like your Arduino's 5V pin).
• Standard SPI Interface: Communicates using the common and fast SPI protocol, making it easy to integrate with a wide range of microcontrollers and supported by standard libraries.
• Easy to Use: Features a spring-loaded (push-push) Micro SD socket for easy card insertion and removal.
• Secure Mounting: Includes four M2 mounting holes for easy and secure installation in your project enclosure.
