Compact and Versatile Micro SD Interface
This Micro SD Card Adapter Module provides a reliable way to read and write data on Micro SD and SDHC memory cards using a SPI interface. Designed especially for embedded systems and compatible microcontroller platforms like Arduino and Raspberry Pi, it simplifies data storage integration.
The module features a standard SPI communication protocol, enabling easy connection to various development boards and quick software integration with existing SD card libraries.
Built-in Level Conversion for Broad Compatibility
Equipped with an integrated level regulator and conversion circuitry, the adapter supports both 3.3V and 5V signal levels. This design ensures safe and seamless operation across different microcontroller interfaces without additional hardware. The module converts signals in both directions, including the MISO line, to 3.3V logic levels.
- Operates at 4.5V to 5.5V DC supply voltage
- Supports 3.3V and 5V logic signals
- Protects microcontrollers from voltage mismatches
Easy Integration and Usage
The Micro SD card slot uses a self-deck type connector allowing simple card insertion and removal. This design minimizes handling issues and maintains secure connections during operation, ideal for development and prototype environments.
Additionally, the control interface provides clearly labeled pins (GND, 3V3, MISO, MOSI, CLK, CS) to facilitate straightforward wiring and integration into any SPI-enabled system.
- Self-deck Micro SD card connector for convenience
- Standard SPI pin layout for quick setup

Thank you very much
That's good.
This sd card reader works perfectly fine, i used it in a raspberry pi pico project to read images and display them to a screen its pretty simple to use once you figure it out π
Ok
