GMOD-MicroSD – MicroSD Card Storage Module for Embedded Systems (SPI/SDIO/SDMMC Interface)
The GMOD-MicroSD is a compact MicroSD card breakout module designed for easy integration of removable storage into embedded systems. It operates over an SPI interface and is ideal for microcontrollers like the GLYPH, Arduino, ESP32, STM32, and Raspberry Pi. This module allows users to log data, store files, or run lightweight file systems like FAT32, making it perfect for IoT, data logging, and multimedia applications.
A robust card socket ensures good contact with MicroSD cards, and all necessary signals are broken out to standard 2.54mm headers for breadboard compatibility. You can read more about this in this documentation : G-Mod MicroSD Module
