Compact and Versatile Storage Module
This Micro SD Card Reader Module provides a reliable way to expand storage for your DIY electronics projects. Its compact size (18.5mm x 17.5mm) makes it ideal for space-conscious applications on breadboards or PCBs.
Designed for makers with soldering skills, the module allows you to configure pin headers vertically or at right angles to fit your project layout perfectly.
Safe 3.3V Operation and Level Shifting
Featuring an onboard 3.3V regulator and level shifting circuit, the module safely bridges the voltage gap between 5V microcontrollers and 3.3V SD cards. This ensures stable communication and protects your components from electrical damage.
Broad Compatibility and Standard SPI Interface
The module supports standard SPI communication, widely supported across Arduino, ESP32, STM32, Raspberry Pi Pico, and similar development boards. It works seamlessly with FAT16 and FAT32 formatted Micro SD cards, ideal for data, image, or configuration file storage.
DIY Installation for Custom Integration
Pin headers are supplied but not soldered, granting flexibility to choose orientation based on your enclosure or project design. Basic soldering skills are required to assemble the module for your application.
