Just passing along an issue I had with your recent posting on Micro SD card – no action needed

I ran into a problem with your tutorial on using a mirco SD card reader with ESP32. I was getting an error of “card not mounted”. After some research, I discovered that instead of using the 3.3V pin, I needed to power the card reader from the 5V pin of the ESP32. The card reader I used was the HiLetgo micro SD TF card adapter. After making that change, it worked fine.
