is SD_A_VSEL input or output?

  • Hello,

    in the domentation of PicoCore MX8MN the pin J2-54 is mentioned as input.

    Below in chapter 4.2 it is mentioned as output.

    What should I do with this pin? I guess it must be left unconnected.

    Thank you for reply.

    Best regards,


  • 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,
