    FX3S 4-Wire microSD PCB Design ???

    DragonflySynths

      I notice that 4-wire designs are absent from AN70707 PCB Guidelines. Can you please verify the feasibility of my proposed 4-wire microSD connections? In particular, that I am free to ignore signal WP, which does not exist on my microSD connector. VIO2 working voltage is 3.3V. What considerations are required to lower this voltage to 1.8V?

       

       

      TIA!
