Micro SD Card Module, SPI, 3.3V, Headers Unsoldered, for Arduino, ESP32 and STM32

3.3V SPI Micro SD Card Module for Arduino & ESP32 – Flexible Installation, Reliable Storage! Key Features & Benefits： ✅ Safe 3.3V Operation & Level Shifting: Onboard 3.3V regulator and level shift circuit ensure safe communication between 5V Arduino and 3.3V SD card, protecting your components. ✅ Flexible DIY Installation: Headers NOT pre-soldered, allowing vertical or right-angle mounting to fit your project enclosure and layout. ✅ Standard SPI Interface: Uses universal SPI protocol, compatible with Arduino Uno, ESP32, STM32, and more, with extensive library support. ✅ Broad Compatibility: Supports Micro SD cards formatted with FAT16/FAT32, ideal for data logging, image storage, and configuration files. ✅ Compact Design: Small 18.5mm x 17.5mm footprint saves space on breadboard or PCB after assembly. Product Description： This Micro SD card module is designed for embedded projects requiring reliable, long-term storage for data logging, media, or system configuration. Note: Headers require soldering, suitable for users with soldering experience. 🚨 Important Notes / How to Use： Soldering Required: Headers are included but NOT soldered. You must solder them before use. Basic soldering skills and tools are needed. Voltage Warning: This is a 3.3V module. Input voltage must be 3.3V. Connecting to 5V will permanently damage the module and SD card. For Experienced Users: Intended for users comfortable with soldering and circuit integration.
