is SD_A_VSEL input or output?

  • Hello,


    Sorry for the mistakes in our documentation. We are going to correct them as soon as possible. Thank you for your kind feedback!


    SD_A_VSEL is actually an output pin to set the voltage level of SDIO_A Pins between 1.8V and 3.3V. If you don't need to select voltage level externally from the baseboard (e.g. with a switch) you can left this pin unconnected.



    I hope the answer was helpful for you!


    Best regards,

    Meric
