At this moment i implement SC Card support for NanoVNA H4, it very simple and good work. Use SPI interface some as display, need only SD_CS,?SPI_MOSI,?SPI_SCLK signals (SPI shared vs display and work on some speed), good if exist SD_CD (for SD card insert);
It very low cost solution, need ~7kB flash and ~600 bytes RAM for full dile read/write Fat16/32 support (can extend, use FatFS lib)
