About this item

The Mini Micro SD Card Reader Module is a compact, easy-to-use breakout board designed to add microSD memory capability to microcontroller projects. It features a standard SPI interface—GND, VCC, MISO, MOSI, SCK, and CS—for seamless integration with platforms like Arduino, ESP32, STM32, and more. A built-in 3.3V LDO regulator and level conversion circuitry enable safe operation even when powered from 5V sources, making it versatile across systems. This module supports FAT-formatted microSD and SDHC cards (typically up to 32GB)—perfect for data logging, media storage, or extending memory for DIY embedded applications. Its slim footprint (approximately 18×20mm) and lightweight design (~4g) are ideal for breadboard setups and compact enclosures. Even when no card is inserted, it consumes minimal power—with a quiescent current around 16µA—making it suitable for battery-powered or low-power setups. In short, the Mini Micro SD Card Reader Module offers a reliable, cost-effective way to integrate external storage into embedded projects. Whether you're building a data logger, multimedia recorder, or expandable IoT device, it delivers robust performance in a small, beginner-friendly package.
