Hi I am in a proyect where I have to write sensor Data into a SD card, however I have some problems with the power supply of my arduino nano 33 iot.
My SD card reader has a 3.3V pin, so it shouldn´t be a problem to powered it with my arduino nano. However when I tried to do it, keeps saying Failed to initialize. I Know it is not a problem with my code and the conection with MISO, MOSI, CS, SCK pins, due to the fact that if I keep this pins conected to the arduino nano, but the GND and 3.3V pins conected to an arduino UNO it works perfectly
How could I power this SD card reader with my arduino nano?
