SD Card operations on ESP32 SD card or Secure Digital card can store and retrieve data locally. An SD card is a non-volatile memory card used widely in portable devices, such as mobile phones, digital cameras, GPS navigation devices, and tablet computers. They come with the SD card library examples and you shouldn't modify them. To try other examples to work with the microSD card, go to File > Examples > SD(esp32). Uploading the Code. Now, upload the code to your ESP32. Make sure you have the right board and COM port selected. Demonstration. Open the Serial Monitor at a baud rate of 115200. Image: MicroSD to SD card adapter wired up for SPI interface. Note to self: Perhaps a black mat isn't the best background for photos! Using SD cards with the Arduino (5V micrcontrollers) The catch is that this will only work without modification on 3.3V microcontrollers like the ESP8266 and ESP32. Demo 7: How to use Arduino ESP32 to store data to microsdcard (Soft SPI and Hard SPI) Tech It Yourself... I have same SD card module but I always get sd card initalization failed message. I am using LOLIN32 board with selected pins 32, 23, 19, 18. My first issue is that it looks like the SD card uses most of the remaining GPIO pins, which would mean I couldn't use the servos. That may end up precluding me from using the SD card (which isn't horrible, but the card would make life so much easier). Regardless, without the servos attached/enabled I still can't get the SD card to even function. Do I need any additional modules, like Arduino SD module? No, just wire your SD card directly to ESP32. What is the difference between SD and SD_MMC libraries? SD runs on SPI, and SD_MMC uses the SDMMC hardware bus on the ESP32. Can I change the CS pin? Yes, just use: SD.begin(CSpin)

It's ESP32 wifi & BT board with Mciro SD card, USB 2 USART Chip cp2104, Compatible with Arudino Interface. Not directly related but I was just testing a micro SD card setup on a NodeMcu32s under Arduino. The ESP32 hardware seems fussy about the type of SD card, the one I was intially testing with was not recognised at all, but it works fine on say a Arduino Pro Mini. This example doesn't utilize card detect (CD) and write protect (WP) signals from SD card slot. With the given pinout for SPI mode, same connections between the SD card and ESP32 can be used to test both SD and SPI modes, provided that the appropriate pullups are in place.
