I recently got a AURSINC NanoVNA-H with a micro SD card slot and every time I try to save a screen shot it says "FAIL TO WRITE". I am using a SanDisk 64GB microSD card and I can't seem to figure out the problem.
Apparently, the big SD cards don't support the SPI mode interface, which is what the NanoVNA uses.? Stick with 32GB or smaller. (and, given the existence of counterfeit SD cards, it's always good to check it on some other computer).
