SD card on different pins



  • Hi,

    is possible to have SD card on non default pins?
    default are
    P8: DAT0, P23: SCLK and P4: CMD

    For i2c we can specify pins parameter but i do not see same for SD

    Thank you for detailed answer

    Not in SDIO mode as it's currently, SDIO is considered fast signals and don't go through the ESP32 internal mux which allows remapping other signals.

    It may be possible using the slower SPI mode.
