    Psoc 4 Suuply in 5V and SD card supply with 3.3V

    user_496198631

      Hi everyone,

       

      I've got some trouble with my PCB card. I have Three PSOC 4 CY8CKIT-142 supply with 5V and Three SD card socket supply by a different 3.3V.

      The three PSOC 4 have the same code and project. But there is a little problemn, one of the Card works perfectly fine, but the two others don't work.

      Does the supply of the PSOC 4 can be a probleme to discuss with SPI for the SD Card, did i need to supply the PSOC 4 in 3.3 V ?
