Setting Up and Using an SD Card with ESP32

To effectively utilize an SD card with your ESP32, you'll need a MicroSD card reader module or a development board that already has an SD card slot. Many affordable Micro SD Card Adapter Module Reader for Arduino, ESP32 units are available, typically communicating via SPI.This module (MicroSD Card Adapter) is a Micro SD card reader module thatreads and writes through the file system and SPI interface controller. When connecting such an adapter, ensure correct pin assignments for SPI communication, including MOSI, MISO, SCK, and CS (Chip Select).

For successful operation, it's crucial to properly insert the SD card into the SD card slot of the extension board or the dedicated slot on your development board. Once the hardware is connected, you can proceed with software integration. The process often involves initializing the SD card and then using file system operations to read and write data. Libraries like the SD card library within the Arduino IDE or the SD SPI host driver in ESP-IDF provide the necessary functions. For MicroPython users, dedicated examples and libraries exist for MicroPython SD card ESP32 integration, making it straightforward to read and write text files on a MicroSD card.ESP32: Guide for MicroSD Card Module using Arduino IDE
